postMessage is unreliable on first load — SW may not be active yet.
IndexedDB is shared between page and SW, so the token is always
available regardless of SW lifecycle timing.

Add a Service Worker that intercepts /api/* requests and injects the
Bearer token. This allows <audio> and <img> elements to use direct
URLs instead of downloading entire files as blobs first.
- Audio now streams progressively (no full download before playback)
- Cover art loads via regular <img src> (SW adds auth header)
- Remove blob-based preloadStream, fetchCoverBlob, useCoverUrl hook
- Register SW in main.tsx, token synced via postMessage
