feat(mukke): display album cover art in library, playlists, and song lists

Add batch cover-url endpoint (POST /library/cover-urls) to efficiently
resolve multiple cover art presigned URLs in a single request. Integrate
cover art display across all UI surfaces: album grid, album detail header,
song list thumbnails, playlist grid, and playlist detail song list.
