The music feature is retired: delete the Media tab, MediaAPI, MediaPlayerController, PinnedMediaResourceLoader, MediaPanelView, the media_state control publish, media scope handling in VoiceSession, the volume setting, and all media tests. App is now Talk + Activity tabs. Backend media API in hope-voice-api is untouched (still serves the web UI).
