feat: Add collection caching for improved performance
- Added _tubeArchivistCollectionId field to cache collection GUID on startup - Added CacheTubeArchivistCollectionId() to find and cache collection once - Added RefreshTubeArchivistCollectionId() to update cache on config changes - Added IsItemInTubeArchivistCollection() helper for efficient validation - Updated PluginConfiguration.CollectionTitle to trigger cache refresh on change - Updated OnPlaybackProgress to use cached ID for O(1) validation This eliminates repeated database lookups (3 per playback event) by caching the collection ID once at startup. For libraries with thousands of movies, this significantly reduces overhead when non-TubeArchivist media is played. Performance improvement: - Before: 3 calls per playback event for all media types - After: 0 calls for rejected media (type check), 1-3 for Episodes only
