audioService.ts rewritten from ~850 lines to ~130:
- Remove custom logging system with throttle that suppressed ERROR logs
- Remove AudioContext management entirely (initializeAudioContext,
handleAudioContextResume, setupAudioContext, shareAudioContextWithWaveSurfer,
ensureAudioContext). WaveSurfer v7 owns its AudioContext; fighting it caused
prod/dev divergence and silent failures.
- Replace 5-state InitializationState machine + split promise with a single
isReady boolean set in the 'ready' event handler
- Remove retry/debounce logic from play() — these are UI concerns
- Remove dead methods: canPlayAudio (always returned true), getWaveSurferVersion,
updatePlayerState, getAudioContextState, setLogLevel
- Extract destroyWaveSurfer() helper so cleanup is one place
- MiniPlayer now passes songId/bandId to play() (was calling with no args)
- SongPage spacebar handler simplified: just checks isReady from hook
- SongPage no longer imports audioService directly
