feat(web): suggest tracks, my uploads and admin upload queue screens (M5.5)

- Suggest tracks: drag-and-drop of files and folders with relative
  paths, streaming SHA-256 in a Web Worker (hash-wasm), duplicate
  precheck, batch reservation and tus-js-client upload (8 MB chunks,
  4 in parallel, token refresh on 401, resume of failed files).
- My uploads: statuses, rejection reasons, withdraw, quota meter.
- Upload queue (admin): status tabs, possible-duplicate filter, batches,
  metadata and storage editing, bulk approve / reject with a reason,
  import retry, and the queue settings form.
- Sidebar section for moderators and admins; ru / en strings.
