Replay gain was not working because track objects were created manually without
including replay gain metadata from the Subsonic API response.
Changes:
- Add songToTrack() helper function to properly map SubsonicSong to Track with
replayGainTrackDb, replayGainAlbumDb, and replayGainPeak fields
- Add audio_update_replay_gain Tauri command for dynamic volume recalculation
when replay gain settings change mid-playback
- Add updateReplayGainForCurrentTrack() to recalculate volume when toggling
replay gain setting
- Fetch fresh track data on cold resume (app relaunch) to ensure replay gain
values are current from server
- Update all files that create track objects to use songToTrack()
Fixes issue where toggling replay gain ON/OFF or changing between track/album
mode had no effect on currently playing or newly played tracks.
