fix(ui): split album and track artists (OpenSubsonic) (#696)

* fix(ui): split OpenSubsonic album and track artists in header and player

Album detail header uses albumArtists from album or child songs; player bar,
mobile player, and mini player use structured track artists with per-id links.
Adds deriveAlbumHeaderArtistRefs helper and OpenArtistRefInline.

Fixes #552

* docs: changelog and credits for OpenSubsonic artist links (PR #696)
