Previously priority sorting was alphabetical (high < low < medium < urgent)
instead of by importance. Now uses Django Case/When to map priority strings
to numeric values: urgent=4, high=3, medium=2, low=1.
Fixes both queryset sorting and list sorting for overdue filter.

Middleware now:
- Detects mobile app vs browser via User-Agent
- Mobile app: Removes frame-blocking headers (allows iframe)
- Browsers: Adds CSP and X-Frame-Options headers (security)
This ensures:
✓ Browsers get full CSP protection
✓ Mobile app can embed content
✓ No need for django-csp package
✓ All security managed in one place

The CSP_FRAME_ANCESTORS = ("'none'",) setting in production.py was
blocking iframe embedding even after removing X-Frame-Options.
Updated middleware to:
- Detect Android WebView via 'wv' in User-Agent (more reliable)
- Remove both X-Frame-Options AND Content-Security-Policy headers
- This allows mobile app iframe embedding while keeping browser protection

Created Django middleware that detects requests from the KeepItGoing
mobile app (via User-Agent) and removes X-Frame-Options header to
allow iframe embedding.
Changes:
- Created tasks/middleware/mobile_app.py with AllowMobileAppFramingMiddleware
- Added middleware to settings after XFrameOptionsMiddleware
- Detects Capacitor WebView User-Agent patterns
- Removes X-Frame-Options only for mobile app, keeps protection for browsers
This allows the mobile app to embed the website in an iframe while
maintaining clickjacking protection for regular web browsers.

Remove duplicate AddField operation for tag.user field in
tasks/migrations/0002_initial.py. The migration was attempting
to add the user ForeignKey field twice, causing PostgreSQL to
fail with "column 'user_id' of relation 'tags' already exists".

Changes:
tasks/serializers.py (TaskSerializer):
- Added __init__() method to override tag_ids queryset
- Filter Tag.objects.all() to Tag.objects.filter(user=request.user)
- Only allows users to assign their own tags to tasks
- Prevents information disclosure via tag enumeration
Security impact:
- Prevents users from accessing other users' tag IDs
- Blocks unauthorized tag association
- Protects tag privacy and prevents enumeration attacks
- Enforces proper authorization on tag-task relationships
