fix(album-card): per-artist click on multi-artist albums (#767)

* refactor(album): rename SubsonicAlbum.albumArtists to artists per OpenSubsonic spec

The OpenSubsonic AlbumID3 object exposes structured album-artist credits as
`artists` (not `albumArtists`); psysonic's internal type used the wrong name,
so `album.albumArtists` was always undefined on the Subsonic responses
Navidrome returns. `deriveAlbumHeaderArtistRefs` therefore never hit its
album-level branch — only the song-level fallback was carrying the multi-
artist split on the album-detail header.

- Rename the field on `SubsonicAlbum` and add the spec-defined `displayArtist`
  string alongside it.
- Extract `deriveAlbumArtistRefs(album)` for the common case where only the
  album object is available (cards, rails); `deriveAlbumHeaderArtistRefs`
  now uses it after the song-level fallback. The song-level `albumArtists`
  field is unchanged (the spec does name it that way on child songs).
- Tests cover both helpers and the legacy `artist` + `artistId` fallback.

* fix(album-card): per-artist click on multi-artist albums

The artist subtitle under an album card rendered the full `album.artist`
string ("Melvins • Napalm Death") as a single link that always navigated to
`album.artistId`. On the artist-detail page that id is the page's own
artist — so the click resolved to the URL the user was already on and the
router silently no-op'd, with no visible effect.

Render through the existing `OpenArtistRefInline` component instead, fed
from the structured `artists` array via `deriveAlbumArtistRefs`. Each
artist becomes its own ·-separated link; the single-artist fallback is the
same legacy `artist` + `artistId` pair as before, so the behaviour on
servers that don't expose the structured field is unchanged.

* docs(changelog): note PR #767 under Fixed in v1.46.0
