feat: Add VLC service for sound playback and management

- Implemented VLCService to handle sound playback using VLC.
- Added routes for soundboard management including play, stop, and status.
- Introduced admin routes for sound normalization and scanning.
- Updated user model and services to accommodate new functionalities.
- Enhanced error handling and logging throughout the application.
- Updated dependencies to include python-vlc for sound playback capabilities.
