feat(artist): sort albums by year on artist detail (#877)

* feat(artist): year sort for albums section on artist detail

Add a sort dropdown next to "Albums by …" with release-type grouping (default),
newest-first, and oldest-first by album year.

* chore: note PR #877 in CHANGELOG and settings credits

* fix(artist): toggle year sort inside release groups, session per server

Replace dropdown with a click-to-toggle newest/oldest button. Keep release-type
blocks; sort albums by year within each group. Persist order in session store.
