Library files now move to a configurable-retention trash bin on delete
instead of being hard-deleted from disk (default 30 days). Admins get a
"Purge old" bulk action on the File Manager with a live preview, plus an
optional auto-purge setting in Settings → File Manager that runs the same
operation once per 24h when enabled (default off). Regular users see and
manage their own trashed files; admins see everyone's. External (linked)
files bypass trash since their bytes aren't under Bambuddy's control.
- New `library:purge` permission (admin-only by default)
- Nullable indexed `deleted_at` column on library_files; dialect-aware
ALTER TABLE so the column actually gets added on PostgreSQL (raw
DATETIME is SQLite-only syntax)
- New `LibraryFile.active()` classmethod; every query site routed through
it so trashed rows don't leak into listings, print dispatch, MakerWorld
dedupe, or stats
- Trash page: select-all + bulk restore/delete, per-row checkboxes, wider
layout so datetime columns don't clip
- Auto-purge: 24h throttle via `library_auto_purge_last_run` setting so
the 15-minute sweeper cadence still runs the purge at most once per day
- Save toast wired into every trash/auto-purge setting change
- 17 new backend integration tests (service + routes + auto-purge throttle),
8 new frontend tests, localised across all 8 UI languages
- Wiki + website feature entries updated
