Docker Integration Test Fix
The /api/v1/settings endpoint was returning 404 because:
1. The route was defined at /settings/ (with trailing slash)

Fixes:
- Added routes for both with and without trailing slash in settings.py and notification_templates.py
- Updated catch-all in main.py to raise proper HTTPException for API routes
