Codebase audit fixes: stability, performance, accessibility

- Add threading.Lock for position cache thread safety
- Add shutdown_executor() for clean ThreadPoolExecutor cleanup
- Dedicated ThreadPoolExecutors for script/callback execution
- Fix Mutagen file handle leaks with try/finally close
- Reduce idle WebSocket polling (0.5s → 2.0s when no clients)
- Add :focus-visible styles for playback control buttons
- Add aria-label to icon-only header buttons
- Dynamic album art alt text for screen readers
- Persist MDI icon cache to localStorage
