Dries Peeters 94e8e49439 feat: Add HTTPS support with mkcert and automatic SSL configuration
Add comprehensive HTTPS support with two deployment options:
- mkcert for local development with trusted certificates
- Automatic SSL with Let's Encrypt for production

HTTPS Implementation:
- Add docker-compose.https-mkcert.yml for local HTTPS development
- Add docker-compose.https-auto.yml for automatic SSL certificates
- Create Dockerfile.mkcert for certificate generation
- Add setup scripts (setup-https-mkcert.sh/bat)
- Add startup scripts (start-https.sh/bat)
- Add certificate generation script (generate-mkcert-certs.sh)

CSRF and IP Access Fixes:
- Fix CSRF token validation for IP-based access
- Add CSRF troubleshooting documentation
- Update configuration to handle various access patterns

Documentation:
- Add HTTPS_MKCERT_GUIDE.md with setup instructions
- Add README_HTTPS.md with general HTTPS documentation
- Add README_HTTPS_AUTO.md for automatic SSL setup
- Add AUTOMATIC_HTTPS_SUMMARY.md
- Add CSRF_IP_ACCESS_FIX.md and CSRF_IP_FIX_SUMMARY.md
- Add docs/CSRF_IP_ACCESS_GUIDE.md
- Update main README.md with HTTPS information

Configuration:
- Update .gitignore for SSL certificates and nginx configs
- Update env.example with new HTTPS-related variables
- Update docker-compose.yml with SSL configuration options

This enables secure HTTPS access in both development and production
environments while maintaining compatibility with existing deployments.

# CSRF SSL Strict Mode
# Set to false if accessing via HTTP (localhost or IP address)

# CSRF Cookie Settings
# Only set these if you need to access the app via IP address or have cookie issues

# CSRF_COOKIE_SAMESITE=Lax # Options: Strict, Lax, None
# CSRF_COOKIE_DOMAIN= # Leave empty for single domain, set for subdomains
# Session Cookie Settings for IP Address Access
# If accessing via IP address (e.g., 192.168.1.100), use these settings:
# SESSION_COOKIE_SAMESITE=Lax # Change to 'None' only if needed for cross-site
# SESSION_COOKIE_SECURE=false # Must be false for HTTP
# TROUBLESHOOTING CSRF issues ("CSRF token missing or invalid" errors):
# 1. SECRET_KEY changed? All CSRF tokens become invalid when SECRET_KEY changes
# 2. Cookies blocked? Check browser settings and allow cookies from your domain
# 3. Behind a proxy? Ensure proxy forwards cookies and doesn't strip them
# 4. Token expired? Increase WTF_CSRF_TIME_LIMIT (in seconds)
# 5. Multiple app instances? All must use the SAME SECRET_KEY
# 6. Clock skew? Ensure server time is synchronized (use NTP)
# 7. Accessing via IP? Set WTF_CSRF_SSL_STRICT=false and SESSION_COOKIE_SECURE=false
# 8. Still broken? Try: docker-compose restart app
# 9. For testing only: Set WTF_CSRF_ENABLED=false (NOT for production!)
# See docs/CSRF_CONFIGURATION.md for detailed troubleshooting
