feat: Support role filters for (album) artist role for Navidrome

- Adds an optional (Navidrome only, currently) field `roles` to type `AlbumArtist`
- `roles` is populated using artist.stats (excludign maincredit)
- `getAlbumList` supports a role filter; if specified, only filter artists with that role (ND only)
- Album list on artist page can filter by role if specified (only one)
- Album query is no longer suspend, as it can change multiple times
