fix(artwork): don't crash the server when a playlist's tracks can't be loaded (#6267)

Playlist().Tracks returns nil when its internal Get fails (for example when the
context is canceled at shutdown), and resolvePlaylist called GetAlbumIDs on it,
panicking with a nil pointer dereference. The artwork drain runs on a bare
goroutine, so the panic killed the whole server.

resolvePlaylist now returns an error when Tracks is nil, and the worker recovers
panics per item: it logs the panic with the item details and stack, and marks
the item as a failed attempt so the rest of the batch still runs.

Fixes #6266
