Implement async series data loading with background processing

- Add loading status fields to AnimeSeries model
- Create BackgroundLoaderService for async task processing
- Update POST /api/anime/add to return 202 Accepted immediately
- Add GET /api/anime/{key}/loading-status endpoint
- Integrate background loader with startup/shutdown lifecycle
- Create database migration script for loading status fields
- Add unit tests for BackgroundLoaderService (10 tests, all passing)
- Update AnimeSeriesService.create() to accept loading status fields

Architecture follows clean separation with no code duplication:
- BackgroundLoader orchestrates, doesn't reimplement
- Reuses existing AnimeService, NFOService, WebSocket patterns
- Database-backed status survives restarts

### Fixed
- **Series Visibility**: Fixed issue where series added to the database weren't appearing in the API/UI
- Series are now loaded from database into SeriesApp's in-memory cache on startup
- Added `_load_series_from_db()` call after initial database sync in FastAPI lifespan

- **Episode Tracking**: Fixed missing episodes not being saved to database when adding new series
- Missing episodes are now persisted to the `episodes` table after the targeted scan
- Episodes are properly synced during rescan operations (added/removed based on filesystem state)

### Added
- **Enhanced Anime Add Flow**: Automatic database persistence, targeted episode scanning, and folder creation with sanitized names
- Filesystem utility module (`src/server/utils/filesystem.py`) with `sanitize_folder_name()`, `is_safe_path()`, and `create_safe_folder()` functions
- `Serie.sanitized_folder` property for generating filesystem-safe folder names from display names
- `SerieScanner.scan_single_series()` method for targeted scanning of individual anime without full library rescan
- Add series API response now includes `missing_episodes` list and `total_missing` count
- Database transaction support with `@transactional` decorator and `atomic()` context manager
- Transaction propagation modes (REQUIRED, REQUIRES_NEW, NESTED) for fine-grained control
- Savepoint support for nested transactions with partial rollback capability
- `TransactionManager` helper class for manual transaction control
- Bulk operations: `bulk_mark_downloaded`, `bulk_delete`, `clear_all` for batch processing
- `rotate_session` atomic operation for secure session rotation
- Transaction utilities: `is_session_in_transaction`, `get_session_transaction_depth`
- `get_transactional_session` for sessions without auto-commit
