Subject: [PATCH] feat(koplugin): bulk download all cloud books from Library
 view (#4751) (#4765)

Downloading a Readest cloud library into KOReader previously required
tapping each book one at a time. Add a "Download all books" action to
the Library view menu that pulls every cloud-only book to the device
in one pass.

- LibraryStore:listCloudOnlyBooks() returns the downloadable
  cloud-present, not-local books for the current user (whole library,
  independent of the active search/group view).
- librarywidget.downloadAll() streams them sequentially via the
  existing syncbooks.downloadBook path inside a Trapper coroutine:
  cancellable progress (Trapper:info Abort/Continue), per-book
  failures skipped and counted, summary toast at the end. Bridges
  downloadBook's sync-or-async callback with a coroutine suspended
  check so it serializes correctly either way.
- Wire the action into the view-menu Actions section.
- Add the new UI strings and translate them across all 33 locales.

Closes #4751
