refactor(web): split AudioContext into context/audio-context module
- types.ts: VisualizerSettings, AudioContextType
- mockTracks.ts: mock track data for initial state
- useAudioContextValue.ts: all state, effects, and actions
- AudioContext.tsx: createContext, useAudio, AudioProvider
- Re-export from context/AudioContext.tsx (useAudio, AudioProvider, VisualizerSettings)
- Fix toggleMute to toggle isMuted (was incorrectly toggling isPlaying)
- 12 tests pass
