* feat(albums): "Artist → Year" sort option
Adds a third album browse sort that groups albums by artist and orders each
artist's albums chronologically (oldest first, title as a same-year tiebreak)
— the double-sort requested in #1113. The local index sorts globally via
[{artist},{year},{name}]; the server fallback fetches by artist and applies the
year ordering per page (Subsonic has no compound sort).
* i18n(albums): Artist → Year sort label (9 locales)
* docs(changelog): add Artist → Year to the album sorting entry (#1120)
