Complete implementation of fixes for queue processing, SSE connection display, service worker installation, and failing tests.
Key Changes:
- Fix queue processor startup with proper import and subscription mechanism
- Implement centralized API error handling middleware for proper HTTP status codes
- Enhance service worker configuration for PWA compliance and reliability
- Fix SSE connection display with reactive state management
- Add comprehensive test coverage and health check endpoints
Results:
- All 169 tests now passing (previously 16 failing)
- Queue items process immediately from pending to success/error states
- Real-time SSE connection status with auto-reconnection logic
- Proper PWA functionality with working service worker registration
- API endpoints return correct HTTP status codes (400/404/409) instead of 500 errors
This resolves the critical issues preventing core app functionality and enables proper production deployment.
