Add support for Album Artist Sort

[martpie]

Fix #941

[Copilot]

Pull request overview

Adds support for sorting/grouping artists using the ALBUMARTISTSORT tag (with a fallback normalization), propagating the new sort metadata from the Rust backend through generated typings into the Artists view UI.

Changes:

• Introduce album_artist_sort on Track and persist it via DB migration + insert/update paths.
• Change artist listing API to return { label, sort_as } and update the Artists route + SideNav grouping to use the sort key for sectioning.
• Add a Rust unit test for the normalization fallback and update mocks/generated typings accordingly.

Pull request overview

Adds backend + frontend support for “Album Artist Sort” to improve artist list ordering/grouping (issue #941), by persisting an album_artist_sort value per track and using it for artist list sorting and side-nav grouping.

Changes:

• Add album_artist_sort to track metadata (Rust Track struct, SQLite schema migration, generated TS typings).
• Update the artists API to return {label, sort_as} objects and use sort_as for UI grouping while keeping label for display/routing.
• Add tests covering artist sorting behavior and normalization fallback.

SortBy.Artist now uses Track.album_artist_sort as the primary key. However, the track edit flow (LibraryAPI.updateTrackMetadata) only updates album_artist (via TrackMutation) and then persists the full Track back to the DB, which can leave album_artist_sort stale after a user renames an album artist. Consider recomputing album_artist_sort when updating tracks (either in the frontend when album_artist changes, or in the backend update_track), so sorting/grouping stays consistent after edits.
