debug: add quality logging to diagnose issue #34

- Log requested vs returned format_id and sample_rate in get_stream_url_with_fallback
- Log quality_str, parsed quality, and format_id in play_track and prefetch_track commands
- Add console.log in getStreamingQuality for frontend debugging

This will help diagnose why 192kHz is played despite lower quality settings.
