fix: resolve silent voice playback on VPS and queue screenshare streams

- Add ffmpeg stderr monitoring to catch audio decoding errors
- Add HTTP timeout parameters (-connect_timeout, -read_timeout) for VPS reliability
- Add URL validation in yt-dlp to ensure audio URLs are resolved
- Add comprehensive logging to mediaController for queue operations
- Add logging to musicPlayer for ffmpeg command execution and errors
- Update musicPlayer test to expect new timeout parameters

Fixes:
1. Silent audio issue: ffmpeg errors are now visible in logs
2. Queue bypass: Added logging to track queue → playback flow
3. VPS network issues: Added timeouts for HTTP stream connections
