AIXF Album Activity 2.3.7.f

AIXF – XFMG Album Last Activity fixes a long-standing UX issue in XenForo Media Gallery:
Albums were sorted only by their creation date, meaning updated albums stayed buried while stale ones stayed on top.

This add-on introduces a new field — last_media_date — and automatically updates it whenever media is added, moved, deleted, or restored. Album listings then sort by this field, ensuring active albums rise to the top (just like forum threads).

• Adds a new last_media_date column to xf_mg_album.
• Updates automatically when:
  • New media is uploaded into an album.
  • Media is moved between albums.
  • Media is deleted/hidden or restored.
• Browse Albums (/media/albums/) and User Albums (/media/albums/users/...) can now sort by Last Activity.
• Admin option: choose default album sort (creation date vs. last activity).
• Backfills existing albums on install (sets last activity to the latest visible media).

1. Upload files to /src/addons/AIXF/AlbumActivity/.
2. Install from AdminCP → Add-ons.
3. Rebuild caches: Tools → Rebuild caches → Rebuild add-on caches.
4. Configure default order: AdminCP → Options → AIXF – Album Activity.

• Safe to uninstall; the last_media_date column remains in place but unused.
