feat: Make user profile pictures persistent across Docker updates

Store user avatars in persistent /data volume instead of application
directory to ensure profile pictures survive container rebuilds and
version updates.

Changes:
- Update avatar upload folder from app/static/uploads/avatars to
  /data/uploads/avatars using existing app_data volume mount
- Modify get_avatar_upload_folder() in auth routes to use persistent
  location with UPLOAD_FOLDER config
- Update User.get_avatar_path() to reference new storage location
- Add migration script to safely move existing avatars to new location
- Preserve backward compatibility - no database changes required

Benefits:
- Profile pictures now persist between Docker image updates
- Consistent with company logo storage pattern (/data/uploads)
- Better user experience - avatars not lost during upgrades
- Production-ready data/code separation
- All persistent uploads consolidated in app_data volume

Migration:
For existing installations with user avatars, run:
  docker-compose run --rm app python /app/docker/migrate-avatar-storage.py

New installations work automatically with no action required.

+# Changelog: Profile Picture Persistence
+
+**Date:** October 22, 2025  
+**Version:** Current  
+**Type:** Enhancement  
+**Breaking Change:** No (backward compatible with migration)
+
+## Summary
+
+Profile pictures (user avatars) now persist between Docker container updates and rebuilds. Previously, avatars were stored in the application directory and would be lost when updating the Docker image.
+
+## Changes
+
+### Modified Files
+
+1. **`app/routes/auth.py`**
+   - Updated `get_avatar_upload_folder()` to use `/data/uploads/avatars` instead of `app/static/uploads/avatars`
+   - Avatars now stored on persistent volume
+
+2. **`app/models/user.py`**
+   - Updated `get_avatar_path()` to reference new storage location
+   - Added comments explaining persistence benefit
+
+### New Files
+
+3. **`docker/migrate-avatar-storage.py`**
+   - Migration script to move existing avatars to new location
+   - Safe to run multiple times
+   - Verifies permissions and provides detailed output
+
+4. **`docs/AVATAR_STORAGE_MIGRATION.md`**
+   - Complete migration guide
+   - Troubleshooting section
+   - Backup recommendations
+
+5. **`docs/AVATAR_PERSISTENCE_SUMMARY.md`**
+   - Quick reference for the change
+   - Migration commands
+   - Verification checklist
+
+6. **`docs/TEST_AVATAR_PERSISTENCE.md`**
+   - Testing guide with step-by-step instructions
+   - Automated test script
+   - Troubleshooting commands
+
+## Technical Details
+
+### Storage Location
+
+| Aspect | Before | After |
+|--------|--------|-------|
+| **Path** | `/app/static/uploads/avatars/` | `/data/uploads/avatars/` |
+| **Volume** | Inside container (ephemeral) | `app_data` volume (persistent) |
+| **Survives Updates** | ❌ No | ✅ Yes |
+| **URL** | `/uploads/avatars/{filename}` | `/uploads/avatars/{filename}` (unchanged) |
+
+### Docker Configuration
+
+- Uses existing `app_data:/data` volume mount
+- No docker-compose.yml changes required
+- Consistent with company logo storage (`/data/uploads`)
+
+### Backward Compatibility
+
+✅ **Fully backward compatible**
+- Existing avatar URLs continue to work
+- Database schema unchanged (no migration needed)
+- Old avatars can be migrated with provided script
+- No code changes required for users
+
+## Migration Required?
+
+### New Installations
+✅ **No action needed** — New location used automatically
+
+### Existing Installations with Avatars
+⚠️ **Migration recommended** — Run migration script to preserve existing avatars
+
+```bash
+docker-compose down
+docker-compose run --rm app python /app/docker/migrate-avatar-storage.py
+docker-compose up -d
+```
+
+### Existing Installations without Avatars
+✅ **No action needed** — New location will be used automatically
+
+## Testing
+
+All code changes have been validated:
+- ✅ No linter errors
+- ✅ Code logic verified
+- ✅ Volume mount confirmed in docker-compose.yml
+- ✅ URL structure preserved
+- ✅ Backward compatible
+
+### Recommended Testing
+
+After deployment:
+1. Verify existing avatars display correctly
+2. Upload new avatar and verify persistence after restart
+3. Rebuild container and verify avatars still exist
+4. Check `/data/uploads/avatars/` contains files
+
+See `docs/TEST_AVATAR_PERSISTENCE.md` for detailed testing guide.
+
+## Benefits
+
+1. **🔄 Persistent Storage** — Avatars survive updates and rebuilds
+2. **👥 Better UX** — Users don't lose profile pictures during updates
+3. **🏗️ Production Ready** — Proper separation of persistent data from code
+4. **🔧 Consistent** — Matches company logo storage pattern
+5. **💾 Backup Friendly** — All uploads in one volume (`app_data`)

+Migration Script: Move User Avatars to Persistent Storage
+
+This script migrates user avatar files from the application directory
+(app/static/uploads/avatars) to the persistent /data volume (/data/uploads/avatars).
+
+This ensures profile pictures persist between Docker container updates and rebuilds.
+
+Usage:
+    python migrate-avatar-storage.py
+
+The script will:
+1. Check for avatars in the old location (app/static/uploads/avatars)
+2. Create the new directory structure (/data/uploads/avatars)
+3. Copy all avatar files to the new location
+4. Verify successful migration
+5. Optionally remove old files after confirmation
+
+Note: This is safe to run multiple times - it will skip files that already exist
+in the new location.

+# Avatar Persistence Update - Summary
+
+## Quick Summary
+
+✅ **Profile pictures now persist between Docker updates!**
+
+User avatars are now stored in the persistent `/data` volume instead of the application directory, ensuring they survive container rebuilds and updates.
+
+## What to Do
+
+### For Existing Installations
+
+If you have users with existing profile pictures:
+
+```bash
+# 1. Stop containers
+docker-compose down
+
+# 2. Run migration
+docker-compose run --rm app python /app/docker/migrate-avatar-storage.py
+
+# 3. Start containers
+docker-compose up -d
+```
+
+### For Fresh Installations
+
+Nothing! The new location will be used automatically.
+
+## Changes Made

+# User Avatar Storage Migration Guide
+
+## Overview
+
+As of this update, user profile pictures (avatars) are now stored in the persistent `/data` volume instead of the application directory. This ensures that **profile pictures persist between Docker container updates and rebuilds**.
+
+## What Changed?
+
+### Previous Behavior
+- **Location:** `app/static/uploads/avatars/`
+- **Problem:** This directory is inside the application container, so avatars were lost when updating or rebuilding the Docker image
+- **Impact:** Users had to re-upload their profile pictures after each update
+
+### New Behavior
+- **Location:** `/data/uploads/avatars/`
+- **Solution:** This directory is on the persistent `app_data` Docker volume
+- **Benefit:** Profile pictures are preserved across all updates and rebuilds
+
+## Migration Required?
+
+**If you have existing user avatars**, you need to run the migration script to move them to the new location.
+
+**If you're setting up a fresh installation**, no migration is needed - the new location will be used automatically.
+
+## How to Migrate Existing Avatars
+
+### Docker Environment
+
+1. **Stop your TimeTracker containers:**
+   ```bash
+   docker-compose down
+   ```
+
+2. **Run the migration script:**
+   ```bash
+   docker-compose run --rm app python /app/docker/migrate-avatar-storage.py
+   ```
+
+3. **Start your containers:**
+   ```bash
+   docker-compose up -d
+   ```
+
+4. **Verify avatars are working:**
+   - Log in to TimeTracker
+   - Check that user profile pictures are displayed correctly
+   - Try uploading a new avatar to confirm uploads work
+
+5. **Optional - Cleanup old files:**
+   After confirming everything works, you can remove the old avatar directory:
+   ```bash
+   docker-compose exec app rm -rf /app/static/uploads/avatars
+   ```
+
+### Bare Metal / Development Environment
+
+1. **Navigate to your TimeTracker directory:**
+   ```bash
+   cd /path/to/TimeTracker
+   ```
+
+2. **Ensure the new directory exists:**
+   ```bash
+   mkdir -p /data/uploads/avatars
+   ```
+
+3. **Run the migration script:**
+   ```bash
+   python docker/migrate-avatar-storage.py
+   ```
+
+4. **Restart your application:**
+   ```bash
+   # Your normal restart command
+   systemctl restart timetracker
+   # or
+   ./restart.sh
+   ```
+
+5. **Verify and cleanup:**
+   Follow steps 4-5 from the Docker instructions above.
+
+## Technical Details
+
+### Files Modified
+
+1. **`app/routes/auth.py`**
+   - Updated `get_avatar_upload_folder()` to use `/data/uploads/avatars`
+   - Comment added explaining the persistence benefit
+
+2. **`app/models/user.py`**
+   - Updated `get_avatar_path()` to use `/data/uploads/avatars`
+   - Added fallback for development environments
+
+3. **`docker-compose.yml`**
+   - Already had `app_data:/data` volume mount (no changes needed)
+
+### Configuration
+
+The avatar location now respects the `UPLOAD_FOLDER` configuration:
+- **Default:** `/data/uploads` (avatars go to `/data/uploads/avatars`)
+- **Configurable:** Set `UPLOAD_FOLDER` in your environment to change the base path
+
+### URL Structure
+
+The public URL structure **remains unchanged**:
+- **URL:** `/uploads/avatars/{filename}`
+- **Route:** Handled by `auth.serve_uploaded_avatar()`
+
+This means existing avatar URLs in the database continue to work without modification.
+
+## Troubleshooting
+
+### Avatars not displaying after migration
+
+1. **Check file permissions:**
+   ```bash
+   docker-compose exec app ls -la /data/uploads/avatars/
+   ```
+   Files should be readable by the app user.
+
+2. **Verify volume mount:**
+   ```bash
+   docker inspect timetracker-app | grep -A 5 Mounts
+   ```
+   Should show `/data` mounted from the `app_data` volume.
+
+3. **Check migration log:**
+   Re-run the migration script to see if files were actually copied.
+
+### New avatar uploads failing
+
+1. **Check directory permissions:**
+   ```bash
+   docker-compose exec app touch /data/uploads/avatars/.test
+   ```
+   If this fails, fix permissions:
+   ```bash
+   docker-compose exec app chown -R app:app /data/uploads/avatars
+   docker-compose exec app chmod -R 755 /data/uploads/avatars
+   ```
+
+2. **Check disk space:**
+   ```bash
+   docker-compose exec app df -h /data
+   ```
+
+### Migration script can't find old directory
+
+This is normal if:
+- You're setting up a fresh installation (no avatars to migrate)
+- Avatars were already migrated previously
+- No users have uploaded avatars yet
+
+The script will create the new directory structure automatically.
+
+## Benefits of This Change
+
+✅ **Persistent Storage:** Profile pictures survive Docker updates and rebuilds  
+✅ **Consistent with Logos:** Company logos already use `/data/uploads` (consistency)  
+✅ **Better UX:** Users don't lose their profile pictures during updates  
+✅ **Production Ready:** Proper separation of persistent data from application code  
+✅ **Backup Friendly:** All persistent uploads are in one volume (`app_data`)  
+
+## Backup Recommendations
+
+Since avatars are now on the `app_data` volume, include this volume in your backup strategy:
+
+```bash
+# Backup the entire data volume
+docker run --rm -v timetracker_app_data:/data -v $(pwd):/backup ubuntu tar czf /backup/app_data_backup.tar.gz -C /data .
+
+# Restore the data volume
+docker run --rm -v timetracker_app_data:/data -v $(pwd):/backup ubuntu tar xzf /backup/app_data_backup.tar.gz -C /data
+```
+
+## Questions?
+
+If you encounter any issues with the avatar migration:
+
+1. Check the [Troubleshooting](#troubleshooting) section above
+2. Review the Docker logs: `docker-compose logs app`
+3. Open an issue on GitHub with migration script output

+# Extra Goods Feature
+
+## Overview
+
+The Extra Goods feature allows you to add physical products, services, materials, licenses, and other billable items to both projects and invoices. This extends the time-tracking functionality to support full product and service billing.
+
+## Features
+
+### Core Functionality
+
+- **Add extra goods to projects**: Track products and services associated with a project
+- **Add extra goods to invoices**: Include products and services directly on invoices
+- **Multiple categories**: Organize goods as products, services, materials, licenses, or other
+- **Flexible pricing**: Set quantity and unit price with automatic total calculation
+- **SKU/Product codes**: Track items with unique identifiers
+- **Billable/Non-billable**: Mark items as billable or non-billable
+- **Multi-currency support**: Each good can have its own currency code
+
+### Integration
+
+- **Invoice generation**: Automatically include project extra goods when generating invoices from time entries
+- **Cost tracking**: Extra goods work alongside project costs for comprehensive billing
+- **Reporting**: Goods are included in project totals and invoice calculations
+
+## Data Model
+
+### ExtraGood Model
+
+```python
+class ExtraGood(db.Model):
+    id = db.Column(db.Integer, primary_key=True)
+    
+    # Links (can be associated with project, invoice, or both)
+    project_id = db.Column(db.Integer, nullable=True)
+    invoice_id = db.Column(db.Integer, nullable=True)
+    
+    # Good details
+    name = db.Column(db.String(200), nullable=False)
+    description = db.Column(db.Text, nullable=True)
+    category = db.Column(db.String(50), nullable=False)
+    
+    # Pricing
+    quantity = db.Column(db.Numeric(10, 2), nullable=False, default=1)
+    unit_price = db.Column(db.Numeric(10, 2), nullable=False)
+    total_amount = db.Column(db.Numeric(10, 2), nullable=False)
+    currency_code = db.Column(db.String(3), nullable=False, default='EUR')
+    
+    # Billing
+    billable = db.Column(db.Boolean, default=True, nullable=False)
+    sku = db.Column(db.String(100), nullable=True)
+    
+    # Metadata
+    created_by = db.Column(db.Integer, nullable=False)
+    created_at = db.Column(db.DateTime, nullable=False)
+    updated_at = db.Column(db.DateTime, nullable=False)
+```
+
+### Categories
+
+- **product**: Physical or digital products
+- **service**: Additional services beyond time-tracked work
+- **material**: Materials and supplies used in the project
+- **license**: Software licenses, permits, or other licenses
+- **other**: Any other type of good or service
+
+## Usage
+
+### Adding Extra Goods to a Project
+
+1. Navigate to the project view page
+2. Click "Add Extra Good" or navigate to `/projects/<id>/goods/add`
+3. Fill in the form:
+   - Name (required)
+   - Description (optional)
+   - Category (required)
+   - SKU/Product Code (optional)
+   - Quantity (required, default: 1)
+   - Unit Price (required)
+   - Currency (default: EUR)
+   - Billable checkbox (default: checked)
+4. Click "Add Good"
+
+### Adding Extra Goods to an Invoice
+
+#### Method 1: Direct Addition
+
+1. Navigate to invoice edit page
+2. In the "Extra Goods" section, click "Add Good"
+3. Fill in the good details inline:
+   - Name
+   - Description
+   - Category
+   - Quantity
+   - Unit Price
+   - SKU (optional)
+4. Click "Save Changes"
+
+#### Method 2: Generate from Project
+
+1. Navigate to invoice edit page
+2. Click "Generate from Time/Costs/Goods"
+3. Select extra goods from the project
+4. Click "Add Selected to Invoice"
+5. Project goods will be copied to the invoice
+
+### Managing Extra Goods
+
+#### Editing
+
+- For project goods: Navigate to `/projects/<id>/goods/<good_id>/edit`
+- For invoice goods: Edit directly in the invoice edit form
+
+#### Deleting
+
+- Project goods can only be deleted if not yet added to an invoice
+- Invoice goods are deleted when you remove them from the invoice edit form
+
+#### Viewing
+
+- Project goods list: `/projects/<id>/goods`
+- Invoice goods: Displayed on invoice view and edit pages
+
+## API Endpoints
+
+### Project Extra Goods
+
+- `GET /projects/<id>/goods` - List all goods for a project
+- `POST /projects/<id>/goods/add` - Add a new good to a project
+- `GET /projects/<id>/goods/<good_id>/edit` - Edit form
+- `POST /projects/<id>/goods/<good_id>/edit` - Update a good
+- `POST /projects/<id>/goods/<good_id>/delete` - Delete a good
+- `GET /api/projects/<id>/goods` - JSON API for project goods
+
+### Invoice Extra Goods
+
+Extra goods for invoices are managed through the invoice edit form:
+- `GET /invoices/<id>/edit` - Shows invoice with extra goods
+- `POST /invoices/<id>/edit` - Updates invoice including extra goods
+
+## Database Migration
+
+The extra goods feature requires database migration `021_add_extra_goods_table.py`.
+
+To apply the migration:
+
+```bash
+# Using Alembic
+alembic upgrade head
+
+# Or using Flask-Migrate
+flask db upgrade
+```
+
+## Calculations
+
+### Invoice Totals
+
+When calculating invoice totals, extra goods are included:
+
+```python
+items_total = sum(item.total_amount for item in invoice.items)
+goods_total = sum(good.total_amount for good in invoice.extra_goods)
+subtotal = items_total + goods_total
+tax_amount = subtotal * (tax_rate / 100)
+total_amount = subtotal + tax_amount
+```
+
+### Project Value
+
+Extra goods contribute to the total project value:
+
+```python
+total_value = (billable_hours * hourly_rate) + billable_costs + billable_extra_goods
+```
+
+## Best Practices
+
+1. **Use SKU codes**: For recurring products, use SKU codes for easy identification
+2. **Categorize correctly**: Choose the appropriate category for easier reporting
+3. **Set billable flag**: Mark non-billable items appropriately to exclude from client billing
+4. **Link to projects first**: Add goods to projects, then include them in invoices for better tracking
+5. **Update totals**: The system automatically updates totals, but verify before sending invoices
+
+## Permissions
+
+- **Admin users**: Full access to create, edit, and delete extra goods
+- **Regular users**: Can add goods they created; cannot delete goods added to invoices
+
+## Reporting and Analytics
+
+Extra goods data is available for:
+- Project cost tracking and budgeting
+- Invoice generation and billing
+- Category-based analysis
+- Client billing summaries
+
+## Troubleshooting
+
+### Common Issues
+
+**Good won't delete from project**
+- Check if the good has been added to an invoice
+- Goods added to invoices cannot be deleted from projects
+
+**Total amount incorrect**
+- The system auto-calculates `total_amount = quantity * unit_price`
+- If you need to override, modify quantity or unit price
+
+**Good not appearing on invoice**
+- Ensure the good is marked as billable
+- Check that `invoice_id` is not already set to another invoice
+- Verify the good belongs to the project linked to the invoice
+
+## Future Enhancements
+
+Potential future improvements:
+- Inventory tracking integration
+- Automated pricing from product catalog
+- Volume discounts
+- Tax rules per product category
+- Multi-unit conversions
+
+## Support
+
+For issues or questions about the extra goods feature:
+1. Check the application logs for error details
+2. Verify database migration is applied
+3. Review the model tests in `tests/test_extra_good_model.py`
+4. Check the route implementations in `app/routes/invoices.py` and `app/routes/projects.py`

+# Testing Avatar Persistence
+
+## Quick Test Checklist
+
+Use this checklist to verify that profile pictures persist correctly across container updates.
+
+### Prerequisites
+
+- TimeTracker is running
+- At least one user account exists
+- You have admin access (if testing other users)
+
+### Test Steps
+
+#### 1. Upload a Profile Picture
+
+1. Log in to TimeTracker
+2. Navigate to Profile → Edit Profile
+3. Upload a profile picture
+4. Save and verify the picture displays
+
+**Expected Result:** ✅ Avatar displays in header and profile page
+
+---
+
+#### 2. Verify Storage Location
+
+```bash
+# Check that the avatar was saved to /data volume
+docker-compose exec app ls -la /data/uploads/avatars/
+
+# You should see files like: avatar_1_a1b2c3d4.png
+```
+
+**Expected Result:** ✅ Avatar file exists in `/data/uploads/avatars/`
+
+---
+
+#### 3. Test Persistence Across Restart
+
+```bash
+# Restart the container
+docker-compose restart app
+
+# Wait for container to be healthy
+docker-compose ps
+```
+
+1. Log back in to TimeTracker
+2. Check if your profile picture still displays
+
+**Expected Result:** ✅ Avatar still displays after restart
+
+---
+
+#### 4. Test Persistence Across Rebuild
+
+```bash
+# Stop and remove containers
+docker-compose down
+
+# Rebuild the image (simulates an update)
+docker-compose build app
+
+# Start containers
+docker-compose up -d
+
+# Wait for startup
+sleep 10
+```
+
+1. Log in to TimeTracker
+2. Check if your profile picture still displays
+
+**Expected Result:** ✅ Avatar persists even after container rebuild
+
+---
+
+#### 5. Test New Avatar Upload
+
+1. Go to Profile → Edit Profile
+2. Upload a different profile picture
+3. Verify the new picture displays
+
+**Expected Result:** ✅ New avatar displays correctly
+
+---
+
+#### 6. Test Avatar Removal
+
+1. Go to Profile → Edit Profile
+2. Click "Remove current picture"
+3. Verify the avatar is removed and initials are shown
+
+**Expected Result:** ✅ Avatar removed, fallback to initials display
+
+---
+
+#### 7. Verify Old Location is Empty (After Migration)
+
+```bash
+# Check old location (should be empty after migration)
+docker-compose exec app ls -la /app/static/uploads/avatars/ 2>&1
+```
+
+**Expected Result:** ✅ Directory doesn't exist or is empty
+
+---
+
+### Test Matrix
+
+| Test Case | Expected Behavior | Status |
+|-----------|-------------------|--------|
+| Upload avatar | Saved to `/data/uploads/avatars/` | ⬜ |
+| Display avatar | Shows in header & profile | ⬜ |
+| Container restart | Avatar persists | ⬜ |
+| Container rebuild | Avatar persists | ⬜ |
+| Upload new avatar | Old file removed, new file saved | ⬜ |
+| Remove avatar | File deleted, fallback to initials | ⬜ |
+| Volume check | Files in `/data/uploads/avatars/` | ⬜ |
+
+### Troubleshooting
+
+#### Avatar doesn't display after upload
+
+```bash
+# Check file permissions
+docker-compose exec app ls -la /data/uploads/avatars/
+
+# Fix permissions if needed
+docker-compose exec app chown -R app:app /data/uploads/avatars/
+docker-compose exec app chmod -R 755 /data/uploads/avatars/
+```
+
+#### Avatar lost after rebuild
+
+```bash
+# Verify volume is mounted
+docker inspect timetracker-app | grep -A 10 Mounts
+
+# Check if app_data volume exists
+docker volume ls | grep app_data
+
+# Inspect volume
+docker volume inspect timetracker_app_data
+```
+
+#### Migration didn't work
+
+```bash
+# Re-run migration script with verbose output
+docker-compose run --rm app python /app/docker/migrate-avatar-storage.py
+
+# Manually check both locations
+docker-compose exec app ls -la /app/static/uploads/avatars/
+docker-compose exec app ls -la /data/uploads/avatars/
+```
+
+### Automated Test Script
+
+You can also run this automated test (save as `test_avatar_persistence.sh`):
+
+```bash
+#!/bin/bash
+
+echo "Testing Avatar Persistence..."
+echo ""
+
+# Test 1: Check volume mount
+echo "1. Checking volume mount..."
+if docker inspect timetracker-app | grep -q "/data"; then
+    echo "   ✅ Volume mounted"
+else
+    echo "   ❌ Volume NOT mounted"
+    exit 1
+fi
+
+# Test 2: Check directory exists
+echo "2. Checking avatar directory..."
+if docker-compose exec -T app test -d /data/uploads/avatars; then
+    echo "   ✅ Directory exists"
+else
+    echo "   ❌ Directory NOT found"
+    exit 1
+fi
+
+# Test 3: Check write permissions
+echo "3. Checking write permissions..."
+if docker-compose exec -T app touch /data/uploads/avatars/.test 2>/dev/null; then
+    docker-compose exec -T app rm /data/uploads/avatars/.test
+    echo "   ✅ Directory is writable"
+else
+    echo "   ❌ Directory NOT writable"
+    exit 1
+fi
+
+# Test 4: Count avatars
+echo "4. Counting avatar files..."
+count=$(docker-compose exec -T app sh -c 'ls -1 /data/uploads/avatars/ 2>/dev/null | wc -l')
+echo "   ℹ️  Found $count avatar file(s)"
+
+echo ""
+echo "✅ All automated checks passed!"
+echo "📝 Manual testing required: Upload, restart, rebuild tests"
+```
+
+Run with: `bash test_avatar_persistence.sh`
