feat(music): migrate from MPD to Mopidy for better streaming support

- Enhanced MPD config with 16 MB buffer and 30s curl timeout
- Discovered buffer_before_play is deprecated in MPD 0.24.6
- Installed Mopidy with mopidy-mpd extension for MPD protocol compatibility
- Configured Mopidy with 15-second GStreamer buffer for smooth radio streaming
- Analyzed network quality: baroque sonatas radio has 40ms jitter from Germany

MPD limitations:
- No pre-buffer control for streams (buffer_before_play deprecated)
- Fixed 512 KB curl buffer (not configurable)
- No replacement for pre-buffering functionality

Mopidy configuration:
- buffer_time: 15000ms (15 seconds)
- stream timeout: 30000ms
- MPD protocol on port 6600 (existing clients work)
- HTTP interface on port 6680
