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.

 * Same scroll-margin bug as the one fixed by [#764](https://github.com/Psychotoxical/psysonic/pull/764) for the Album Detail "More by …" rail, on four more virtual lists: **Artists grid**, **Artists list**, **Composers list** and the **Tracks** virtual song browser. The virtual wrapper sat below the sticky page header but TanStack measured row positions from the scroll-element top — rows still on screen could unmount, and at larger header offsets the list refused to render at all.
 * The measurement is now a shared `useVirtualizerScrollMargin` hook used by every virtual-list call-site (including the existing `VirtualCardGrid` fix from #764).

+* The artist subtitle under an album card rendered a multi-artist string as a single link to the album's primary `artistId`. On an artist-detail page that id is the page's own artist, so the click resolved to the current URL and the router silently no-op'd — the cursor said clickable, nothing happened.
+* Album cards now use the same `OpenArtistRefInline` component the album-detail header uses: each artist becomes its own ·-separated link. Behaviour on servers that don't expose the structured list is unchanged.
+* Root cause was a stale field name: psysonic's internal type called the OpenSubsonic album-artist array `albumArtists`, but the spec (and Navidrome) returns it as `artists`, so the structured branch never fired and the song-level fallback was carrying the album-detail header on its own.
