Subject: Add folder rename and background update trigger to admin UI

- Admin edit form: "Folder name" field renames the directory on save;
  also moves the thumbnail cache subtree to match the new path
- Admin edit page: "Run Update" button spawns update.rb in a background
  thread, streams output into a terminal-style log panel via 1.5s polling;
  shows Done/Error status when complete
