When restoring site backups, users frequently hit 403 Forbidden errors because folder permissions or ownership on the Document Root change (e.g., needing 755 permissions or www-data ownership). Currently, fixing this requires SSH access or submitting a support ticket.
Proposed Feature
Add a simple "Fix Permissions & Ownership" button in the File Manager or Site Settings that automatically:
Resets directories to 755 and files to 644.
Restores correct user/group ownership (www-data).
