Improve admin search overlay layout and behaviour

- Widen overlay (300px -> min(520px, 90vw)), centre instead of
  hardcoded left:400px, so it scales from mobile to desktop
- Split title and unique_name into separate JSON fields and DOM
  elements; two-line result layout (bold title, small grey
  monospace path) instead of "Title (path)" wrapping awkwardly
- Add small margin between title and path line
- Fix event handler stacking: keyup/escape/outside-click handlers
  were being rebound on every display_toggle call. Moved all
  bindings to initialize(), display_toggle() now only shows/hides
- Switch search input from keyup to input event, catching paste
  and cut via mouse which keyup misses
- Add Escape key and outside-click to dismiss the overlay
- Stop clearing search box and results on close; reopening now
  preserves prior search, matching standard search UI behaviour
- Link search results to node_path instead of edit_node_path,
  since opening edit auto-locks the node
- Add "press Enter to see all results" hint in dropdown
- Disable browser autocomplete on search input
