- Add error tracking in lifespan context manager
- Only cleanup services that were successfully initialized
- Properly handle startup errors without breaking async context
- Fixes RuntimeError: generator didn't stop after athrow()

 ## TODO List:
-
-### Completed Tasks:
-
-1. ✅ **NFO/Artwork Loading Isolation** (Completed: 2026-01-23)
-    - Task: Ensure during anime add, NFO, logo, art, etc. is loaded only for the specific anime being added
-    - Status: VERIFIED - Implementation is correct
-    - Details: BackgroundLoaderService.\_load_nfo_and_images() correctly passes serie_folder to create_tvshow_nfo(), which only processes that specific series
-2. ✅ **Setup Redirect Flow** (Completed: 2026-01-23)
-    - Task: Implement redirect flow: setup -> loading -> login when user completes setup
-    - Changes:
-        - Added /loading to exempt paths in setup_redirect middleware
-        - Setup page redirects to loading with initialization in background
-        - Loading page connects to WebSocket for real-time progress
-        - After completion, loading redirects to login
-3. ✅ **Close Setup and Loading Pages** (Completed: 2026-01-23)
-    - Task: Make setup and loading pages unavailable after completion to prevent re-access
-    - Changes:
-        - Check if setup is complete before allowing access to /setup
-        - Redirect to login if accessing /setup after completion
-        - Check if initialization is complete before allowing access to /loading
-        - Redirect to login if accessing /loading after initialization complete
-4. ✅ **Fix Loading Page WebSocket Auth** (Completed: 2026-01-23)
-    - Task: Fix 403 Forbidden error on WebSocket connection
-    - Issue: Loading page was connecting to /ws/progress (doesn't exist)
-    - Changes:
-        - Changed WebSocket URL from /ws/progress to /ws/connect (correct endpoint)
-        - Added /ws/connect to exempt paths in auth middleware
-        - Subscribe to 'system' room after connection for progress updates
-        - Fixed message data handling to match WebSocket format
-5. ✅ **Fix WebSocket Room Subscription Format** (Completed: 2026-01-23)
-    - Task: Fix "Invalid room name: ." error
-    - Issue: WebSocket message format was incorrect - sending {action: 'join', room: 'system'} instead of {action: 'join', data: {room: 'system'}}
-    - Changes: Updated loading.html to send correct message format with nested data object
-6. ✅ **Fix Async Generator Exception Handling** (Completed: 2026-01-23)
-    - Task: Fix "RuntimeError: generator didn't stop after athrow()" error during anime add
-    - Issue: get_optional_database_session() async generator wasn't properly handling exceptions
-    - Changes:
-        - Simplified exception handling in both get_database_session() and get_optional_database_session()
-        - Removed nested try-except inside yield that was causing generator issues
-        - Let async context manager handle exceptions naturally
-7. ✅ **Initialization Restart Protection** (Completed: 2026-01-23)
-    - Task: Ensure initialization doesn't restart on server restart by using database flags
-    - Status: VERIFIED - Already implemented correctly
-    - Details:
-        - SystemSettings.initial_scan_completed flag already prevents re-running initialization
-        - initialization_service checks this flag before performing series sync
-        - All initialization steps (scan, NFO, media) have individual completion flags
-        - Server restart properly skips already-completed steps
