feat: Add comprehensive Import/Export system and standardize UI headers

## New Features

### Import/Export System
- Add DataImport and DataExport models for tracking operations
- Implement CSV import for bulk time entry data
- Add support for importing from Toggl and Harvest (placeholder)
- Implement GDPR-compliant full data export (JSON format)
- Add filtered export functionality with date/project filters
- Create backup/restore functionality for database migrations
- Build migration wizard UI for seamless data transitions
- Add comprehensive test coverage (unit and integration tests)
- Create user documentation (IMPORT_EXPORT_GUIDE.md)

### Database Changes
- Add migration 040: Create data_imports and data_exports tables
- Track import/export operations with status, logs, and file paths
- Support automatic file expiration for temporary downloads

## UI/UX Improvements

### Navigation Menu Restructure
- Rename "Work" to "Time Tracking" for clarity
- Rename "Finance" to "Finance & Expenses"
- Add "Tools & Data" submenu with Import/Export and Saved Filters
- Reorganize Time Tracking submenu: prioritize Log Time, add icons to all items
- Expand Finance submenu: add Mileage, Per Diem, and Budget Alerts
- Add icons to all Admin submenu items for better visual scanning
- Fix Weekly Goals not keeping Time Tracking menu open

### Standardized Page Headers
Apply consistent page_header macro across 26+ pages:
- **Time Tracking**: Tasks, Projects, Clients, Kanban, Weekly Goals, Templates, Manual Entry
- **Finance**: Invoices, Payments, Expenses, Mileage, Per Diem, Budget Alerts, Reports
- **Admin**: Dashboard, Users, Roles, Permissions, Settings, API Tokens, Backups, System Info, OIDC
- **Tools**: Import/Export, Saved Filters, Calendar
- **Analytics**: Dashboard

Each page now includes:
- Descriptive icon (Font Awesome)
- Clear title and subtitle
- Breadcrumb navigation
- Consistent action button placement
- Responsive design with dark mode support

## Bug Fixes

### Routing Errors
- Fix endpoint name: `per_diem.list_per_diems` → `per_diem.list_per_diem`
- Fix endpoint name: `reports.index` → `reports.reports`
- Fix endpoint name: `timer.timer` → `timer.manual_entry`
- Add missing route registration for import_export blueprint

### User Experience
- Remove duplicate "Test Configuration" button from OIDC debug page
- Clean up user dropdown menu (remove redundant Import/Export link)
- Improve menu item naming ("Profile" → "My Profile", "Settings" → "My Settings")

## Technical Details

### New Files
- `app/models/import_export.py` - Import/Export models
- `app/utils/data_import.py` - Import business logic
- `app/utils/data_export.py` - Export business logic
- `app/routes/import_export.py` - API endpoints
- `app/templates/import_export/index.html` - User interface
- `tests/test_import_export.py` - Integration tests
- `tests/models/test_import_export_models.py` - Model tests
- `docs/IMPORT_EXPORT_GUIDE.md` - User documentation
- `docs/import_export/README.md` - Quick reference
- `migrations/versions/040_add_import_export_tables.py` - Database migration

### Modified Files
- `app/__init__.py` - Register import_export blueprint
- `app/models/__init__.py` - Export new models
- `app/templates/base.html` - Restructure navigation menu
- 26+ template files - Standardize headers with page_header macro

## Breaking Changes
None. All changes are backward compatible.

## Testing
- All existing tests pass
- New test coverage for import/export functionality
- Manual testing of navigation menu changes
- Verified consistent UI across all updated pages

+
+## Import Guide
+
+### CSV Import
+
+#### CSV Format
+
+The CSV file should have the following columns:
+
+```csv
+project_name,client_name,task_name,start_time,end_time,duration_hours,notes,tags,billable
+Project A,Client A,Task 1,2024-01-01 09:00:00,2024-01-01 10:30:00,1.5,Meeting notes,meeting;planning,true
+Project B,Client B,,2024-01-01 14:00:00,2024-01-01 16:00:00,2.0,Development work,dev;coding,true
+```
+
+#### Column Descriptions
+
+| Column | Required | Description |
+|--------|----------|-------------|
+| `project_name` | Yes | Name of the project |
+| `client_name` | No | Client name (defaults to project name if not provided) |
+| `task_name` | No | Optional task name |
+| `start_time` | Yes | Start time (YYYY-MM-DD HH:MM:SS or ISO format) |
+| `end_time` | No | End time (leave empty if providing duration_hours) |
+| `duration_hours` | No | Duration in hours (alternative to end_time) |
+| `notes` | No | Notes or description |

+- `YYYY-MM-DD HH:MM:SS` (e.g., 2024-01-01 09:00:00)
+- `YYYY-MM-DDTHH:MM:SS` (ISO format)
+- `YYYY-MM-DD` (assumes midnight)
+- `DD/MM/YYYY HH:MM:SS`
+- `MM/DD/YYYY HH:MM:SS`
+
+#### Steps to Import CSV
+
+1. Download the CSV template: Click "Download Template"
+2. Fill in your time entries data
+3. Click "Choose CSV File" and select your file
+4. The import will start automatically
+5. Check the Import History section for results
+
+#### Handling Errors
+
+If some records fail to import:
+- Check the Import History for error details
+- Common errors include:
+  - Invalid date formats
+  - Missing required fields (project_name, start_time)
+  - Invalid duration values
+- Fix the errors in your CSV and re-import
+
+---

+
+## Troubleshooting
+
+### Import Issues
+
+**Problem**: CSV import fails with "Invalid date format"
+- **Solution**: Check date format matches supported formats. Use YYYY-MM-DD HH:MM:SS
+
+**Problem**: "Project name is required" error
+- **Solution**: Ensure every row has a project_name value
+
+**Problem**: Toggl/Harvest import fails
+- **Solution**: 
+  - Verify API credentials are correct
+  - Check date range is valid
+  - Ensure you have access to the workspace/account
+
+**Problem**: Import stuck in "processing" status
+- **Solution**: 
+  - Wait a few minutes (large imports take time)
+  - Check Import History for errors
+  - Try re-importing with smaller date range
+
+### Export Issues
+
+**Problem**: Export download says "expired"
+- **Solution**: Create a new export (exports expire after 7 days)
+
+**Problem**: Export file is empty
+- **Solution**: Check that you have data in the selected date range/filters
+
+**Problem**: ZIP export won't extract
+- **Solution**: Ensure download completed fully, try re-downloading

+---
+
+## Developer Guide
+
+### Adding New Import Sources
+
+To add support for a new time tracker:
+
+1. Create import function in `app/utils/data_import.py`:
+
+```python
+def import_from_new_tracker(user_id, credentials, start_date, end_date, import_record):
+    """Import from new time tracker"""
+    # Fetch data from API
+    # Transform to TimeTracker format
+    # Create records in database
+    # Update import_record progress
+    pass
+```
+
+2. Add route in `app/routes/import_export.py`:
+
+```python
+@import_export_bp.route('/api/import/new-tracker', methods=['POST'])
+@login_required
+def import_new_tracker():
+    # Handle import request
+    pass
+```
+
+3. Add UI in template `app/templates/import_export/index.html`
+
+### Adding New Export Formats
+
+To support a new export format:
+
+1. Add export function in `app/utils/data_export.py`
+2. Update export routes to handle new format
+3. Add format option in UI
+
+---
+
+## FAQ
+
+**Q: How long are exports stored?**
+A: Exports are automatically deleted after 7 days.
+
+**Q: Can I schedule automatic exports?**
+A: Not currently, but this feature is planned.
+
+**Q: What happens to duplicates during import?**
+A: Duplicate entries are imported as separate records. Use the date range and filters carefully.
+
+**Q: Can I import from multiple Toggl workspaces?**
+A: Yes, import from each workspace separately.
+
+**Q: Are imported entries marked differently?**
+A: Yes, imported entries have a `source` field set to 'toggl', 'harvest', 'import', etc.
+
+**Q: Can I undo an import?**
+A: No automatic undo, but you can filter by source and manually delete imported entries if needed.

+
+### Adding New Import Source
+
+```python
+# 1. Add import function in app/utils/data_import.py
+def import_from_new_source(user_id, credentials, start_date, end_date, import_record):
+    """Import from new time tracker"""
+    import_record.start_processing()
+    
+    try:
+        # Fetch data from API
+        data = fetch_from_api(credentials)
+        
+        # Process each record
+        for record in data:
+            # Create TimeEntry
+            time_entry = TimeEntry(...)
+            db.session.add(time_entry)
+            import_record.update_progress(...)
+        
+        db.session.commit()
+        import_record.complete()
+    except Exception as e:
+        import_record.fail(str(e))
+
+# 2. Add route in app/routes/import_export.py
+@import_export_bp.route('/api/import/new-source', methods=['POST'])
+@login_required
+def import_new_source():
+    data = request.get_json()
+    # ... validation ...
+    
+    import_record = DataImport(
+        user_id=current_user.id,
+        import_type='new_source',
+        source_file='...'
+    )
+    db.session.add(import_record)
+    db.session.commit()
+    
+    summary = import_from_new_source(...)
+    return jsonify({'success': True, 'import_id': import_record.id})
+
+# 3. Add UI in app/templates/import_export/index.html
+# Add button and modal form for the new source
+```
+
+### API Usage Examples
+
+**Import CSV via API:**
+```python
+import requests
+
+files = {'file': open('time_entries.csv', 'rb')}
+response = requests.post(
+    'http://localhost:8080/api/import/csv',
+    files=files,
+    cookies={'session': 'your_session_cookie'}
+)
+print(response.json())
+```
+
+**Export GDPR Data:**
+```python
+import requests
+
+response = requests.post(
+    'http://localhost:8080/api/export/gdpr',
+    json={'format': 'json'},
+    cookies={'session': 'your_session_cookie'}
+)
+result = response.json()
+download_url = result['download_url']
+```
+
+**Check Import Status:**
+```python
+import requests
+
+response = requests.get(
+    f'http://localhost:8080/api/import/status/{import_id}',
+    cookies={'session': 'your_session_cookie'}
+)
+status = response.json()
+print(f"Status: {status['status']}")
+print(f"Progress: {status['successful_records']}/{status['total_records']}")
+```
+
+### Running Tests
+
+```bash
+# Run all import/export tests
+pytest tests/test_import_export.py -v
+
+# Run model tests
+pytest tests/models/test_import_export_models.py -v
+
+# Run with coverage
+pytest tests/test_import_export.py --cov=app.utils.data_import --cov=app.utils.data_export
+```
+
+### Database Migration
+
+```bash
+# Apply migration
+flask db upgrade
+
+# Or with Alembic
+alembic upgrade head
+
+# Rollback if needed
+flask db downgrade
+# or
+alembic downgrade -1
+```
+
+## CSV Format Reference
+
+### Required Columns
+- `project_name` - Name of the project
+- `start_time` - Start time (YYYY-MM-DD HH:MM:SS)
+
+### Optional Columns
+- `client_name` - Client name (defaults to project name)
+- `task_name` - Task name
+- `end_time` - End time
+- `duration_hours` - Duration in hours
+- `notes` - Description/notes
+- `tags` - Semicolon-separated tags
+- `billable` - true/false
+
+### Example CSV
+
+```csv
+project_name,client_name,task_name,start_time,end_time,duration_hours,notes,tags,billable
+Website Redesign,Acme Corp,Design,2024-01-15 09:00:00,2024-01-15 12:00:00,3.0,Homepage mockups,design;ui,true

+```
+
+## Security Notes
+
+### Authentication
+- All endpoints require authentication
+- Users can only access their own data
+- Admins can create backups and view all history
+
+### Data Privacy
+- Exports are private to the creating user
+- Files expire after 7 days
+- Secure storage in `/data/uploads`
+
+### CSRF Protection
+- All POST endpoints require CSRF token
+- Automatically handled by the UI
+- API clients must include CSRF token
+
+## Troubleshooting
+
+### Common Issues
+
+**Import fails with "Invalid date format"**
+- Use YYYY-MM-DD HH:MM:SS format
+- Or ISO format: YYYY-MM-DDTHH:MM:SS
+
+**Toggl import returns 401**
+- Check API token is correct
+- Verify workspace ID is valid
+- Ensure you have access to the workspace
+
+**Export download says "expired"**
+- Exports expire after 7 days
+- Create a new export
+
+**Large import is slow**
+- Imports are processed in batches
+- Wait for completion (check Import History)
+- Consider splitting into smaller date ranges
+
+## Performance Tips
+
+1. **Large Imports**
+   - Split into smaller date ranges
+   - Import during off-peak hours
+   - Monitor Import History for progress
+
+2. **Large Exports**
+   - Use filtered exports for specific data
+   - JSON is faster than ZIP for large datasets
+   - Exports are generated asynchronously
+
+3. **Storage Management**
+   - Exports auto-delete after 7 days
+   - Download important exports immediately
+   - Backups should be stored externally
+
