SergeantPanda 7086f41d64 feat(epg): overhaul EPG auto-matching logic and improve performance
- Moved matching logic to a dedicated module for better organization and testability.
- Made single-channel auto-matching asynchronous, allowing for larger EPG libraries without hitting HTTP timeouts.
- Enhanced memory management and throughput during EPG matching, including optimizations for fuzzy matching and bulk processing.
- Fixed various reliability issues in the auto-matching process, ensuring accurate channel assignments and improved UI feedback.
- Updated API views and frontend components to reflect changes in the matching process and provide real-time notifications.
- Added tests for EPG matching functionality and name normalization.
- Single-channel and selected-channel auto-match always run, even when the channel already has EPG assigned; match-all (no channel IDs) still only processes channels without EPG.
