fix: RC3 queue link underline, genre album artist split, Artists "Other" bucket (#977)

* fix: RC3 queue link underline, genre album artist split, Artists "Other" bucket

Three zunoz reports, one change:

- Queue now-playing card: the artist and album links now underline on hover
  (not just recolour), matching clickable names everywhere else. The album
  link sits on .queue-current-sub itself; artist links are nested .is-link
  spans — both selectors covered.

- Genre album cards split multi-artist credits into individual links like the
  rest of the app. Root cause was the local-index genre query hardcoding NULL
  for the album raw_json column, so OpenSubsonic artists[] never reached the
  card and it fell back to the flat "A • B" single link. Select a.raw_json
  instead (parity with the All Albums / advanced-search album queries).

- Artists page alphabet index: # is now digits-only, and a new "Other" bucket
  collects accented Latin (Æ/Ø/Å…) and non-Latin scripts (CJK, Cyrillic, …)
  that previously fell into the # catch-all. Adds artistBucketKey/compareBuckets
  helpers (unit-tested), an OTHER bucket sorted last, and the artists.other
  label across 9 locales.
