maziggy 1bdd7d224a fix(library): sort File Manager by real filesystem mtime, recursively (#2680)
The folder tree's "sort by recent activity" and the file pane's date sort
put external (mapped/NAS) files in a near-random order instead of ls -t's
newest-first. Nothing captured the files' on-disk mtime: the sort keyed off
the DB updated_at/created_at, which for a bulk external scan is the same
scan instant for every row, so a whole block tied and sorted arbitrarily;
only rows Bambuddy had later touched individually looked "partially right."
The tree also bubbled up only immediate child-file activity, so a file added
deep in a subtree never lifted its parent folders.

- Add nullable fs_modified_at to LibraryFile and LibraryFolder (dialect-
  branched migration, mirroring the #2615 dispatching_at pattern).
- External scan records each file's and directory's real os.stat().st_mtime
  and refreshes it on every re-scan, so a file edited over the mount
  re-sorts and existing installs backfill on the next scan.
- list_folders computes each folder's activity as a recursive newest-
  descendant roll-up (post-order), so a fresh deep file lifts every ancestor.
- Folder tree sort and the file pane's date sort now use the real mtime,
  falling back to created_at for managed uploads with none.
- New toolbar toggle shows/hides each item's last-modified date in the right
  pane (grid + list), with strings in all locales.

Store the mtime as naive UTC to match the other timestamp columns so activity
comparisons never mix naive and aware values on either dialect. Covered by
integration tests (mtime capture, re-scan refresh, deep-file recursive bubble,
folder mtime) and a frontend test proving fs_modified_at is preferred over
created_at.
