fix(lint): resolve eslint errors and warnings

- audioService: replace 'as any' with 'as unknown as AudioService' in
  resetInstance() to satisfy @typescript-eslint/no-explicit-any
- SongPage: add isReady to spacebar useEffect deps so the handler always
  sees the current readiness state
- useWaveform: add containerRef to deps (stable ref, safe to include);
  suppress exhaustive-deps for options.onReady with explanation — adding
  an un-memoized callback would cause initialization on every render
