feat: implement NFO ID storage and media scan tracking

Task 3 (NFO data):
- Add parse_nfo_ids() method to NFOService
- Extract TMDB/TVDB IDs from NFO files during scan
- Update database with extracted IDs
- Add comprehensive unit and integration tests

Task 4 (Media scan):
- Track initial media scan with SystemSettings flag
- Run background loading only on first startup
- Skip media scan on subsequent runs

 1. ✅ scanning anime from folder - COMPLETED
    Implemented initial scan tracking using SystemSettings table. Anime folder scanning now only runs during initial setup, not on each application start.
-   - Added SystemSettings model with initial_scan_completed flag
-   - Created SystemSettingsService for managing setup state
-   - Modified fastapi_app.py to check scan completion status on startup

 2. ✅ Nfo scan - COMPLETED
    Implemented initial NFO scan tracking using SystemSettings table. NFO scanning now only runs during initial setup, not on each application start.
-   - Added NFO scanning to startup process in fastapi_app.py
-   - Check initial_nfo_scan_completed flag before running NFO scan
-   - Run NFO scan only on first startup if TMDB API key is configured and NFO features enabled
-   - Mark NFO scan as completed after successful first run

+3. ✅ nfo data - COMPLETED
+   Implemented NFO ID extraction and database storage during NFO scan. TMDB and TVDB IDs are now read from existing NFO files and stored in the database.
+    - Added parse_nfo_ids() method to NFOService to extract IDs from NFO XML
