Fix memory leaks, stale game data, and audio volume fluctuation

Memory: clean observers even during PiP, nil player on tile disappear,
track/cancel Werkout monitor tasks, add highlight player cleanup.
Data: add scenePhase-triggered reload on day change, unconditional
10-minute full schedule refresh, keep fast 60s score refresh for live games.
Audio: set mute state before playback starts, use consistent .moviePlayback
mode, add audio session interruption recovery handler.
