Fix resource leaks, crashes, and add comprehensive error handling 

This commit addresses multiple critical issues in the plugin:

## Fixes
- Fix #29: Crash when playing Live TV (ArgumentException: Guid can't be empty)
- Fix #60: Crash when playing movies outside TubeArchivist library
- Fix resource leak: HttpClient and HttpClientHandler were never disposed
- Fix infinite loop in PluginConfiguration caused by property setters

## Changes

### Resource Management (IDisposable)
- Implement IDisposable pattern for Plugin class
- Properly dispose HttpClient and HttpClientHandler on shutdown
- Unsubscribe from PlaybackProgress and UserDataSaved events
- Prevent memory leaks and socket exhaustion

### Collection Validation with Caching
- Add CacheTubeArchivistCollectionId() for O(1) collection lookups
- Implement IsItemInTubeArchivistCollection() with:
  - Early type checking (reject non-Episode items immediately)
  - Cached collection ID matching for efficient validation
  - Depth limiting (max 10 levels) to prevent infinite loops
  - Null-safe parent chain traversal
- Filter collection query to use Folder type only (avoids ghost CollectionFolder entries)
- Add RefreshTubeArchivistCollectionId() for configuration changes
- Fallback to hierarchy-based checking when cache unavailable

### Async Error Handling
- Convert async void event handlers to proper async void → async Task pattern
- Add top-level exception handling in OnPlaybackProgress and OnWatchedStatusChange
- Wrap async logic in try-catch blocks with proper logging
- Add ConfigureAwait(false) to all await calls

### Configuration Stability
- Add value change checks in PluginConfiguration property setters
- Prevent infinite loops from repeated property assignments during deserialization
- Only refresh cache/reconnect when values actually change

### Debugging & Logging
- Add comprehensive logging throughout collection validation
- Log parent chain traversal for troubleshooting
- Log all collections found during cache initialization
- Add detailed sync progress logging

## Performance Improvements
- Collection validation: O(n) hierarchy traversal → O(1) cached lookup
- Reduced redundant API calls and hierarchy traversals
- Fixed memory leak from undisposed HttpClient

## Testing
All 23 existing tests pass. Changes are fully backward compatible.
