feat: Implement Music Player Service with VLC integration
- Added MusicPlayerService for managing VLC music playback with playlist support. - Implemented methods for loading playlists, controlling playback (play, pause, stop, next, previous), and managing volume and play modes. - Integrated real-time synchronization with VLC state using a background thread. - Added SocketIO event emissions for player state updates. - Enhanced logging for better debugging and tracking of player state changes. fix: Improve SocketIO service logging and event handling - Added detailed logging for SocketIO events and user authentication. - Implemented a test event handler to verify SocketIO functionality. - Enhanced error handling and logging for better traceability. chore: Update dependencies and logging configuration - Added python-vlc dependency for VLC integration. - Configured logging to show INFO and DEBUG messages for better visibility during development. - Updated main application entry point to allow unsafe Werkzeug for debugging purposes.
