docs(user): update admin and collections instructions for sidebar UI

Admin:
- Admin pages live in the sidebar's Administration panel (Dashboard,
  Libraries, Hash Conflicts, Users, Settings)
- Library creation is the Create Library modal (Library Name,
  Description, Library Type); folders are added afterwards by expanding
  the library row and using the Folders section's path input + Browse +
  Add — the old Add Library modal with folder and 'Scan on save' fields
  no longer exists
- Scanning is via the Scanner API or watch mode (File Watcher status on
  the admin dashboard); remove references to the removed per-library
  Rescan button and 'Force Rescan' option

Collections:
- Fill in the empty creating/managing placeholders with the real flow:
  New Collection button, modal fields (name, description, icon grid,
  color swatches), per-collection edit/delete icon buttons, Restore
  System button, and dashboard-section visibility via Customize
  Dashboard
