feat(web): storage admin, search and catalog pages (M2)

- Storage admin: local folders with a folder picker and NFS sources,
  connection test, scan and full scan with live progress, enable,
  disable, delete
- path pattern editor with reorder, examples and a preview table that
  shows which pattern matched and what came from tags; compile errors
  land under the broken pattern
- Library page with counters, scans and unreadable files; search
  reindex for admins
- search box in the top bar: combobox with keyboard navigation, 150 ms
  debounce, cancelled stale requests, "/" and Ctrl+K, layout fix hint
- search page with tabs and paging, artist and album pages, album
  cards and track lists; unavailable tracks are dimmed
