Improve catalog studio UX and aggressive docker cleanup

Catalog Studio:
- Cross-parent drag & drop now uses optimistic updates with rollback
  on failure (no more full tree reload / visible delay)
- Subpage creation adds the node optimistically then refreshes parent
  only (was full tree reload)
- Single page deletion refreshes only the affected parent (was full
  tree reload)
- Root page creation replaces native prompt() with an inline input
  in the root tab bar
- Escape key no longer closes the dialog when an input field is focused
- TreeNodeUpdate type now supports parentId and orderNum for
  optimistic structural changes

Docker:
- docker-prune.sh default mode now aggressively cleans all unreferenced
  build cache, images >1h old, and stopped containers >1h old
  (was 72h/7d/24h which let cache grow past 80% on every push)
