Clear Completed, Clear Failed and Clear All mutated the Zustand store
directly, so the cleared items were never written back to localStorage.
On the next load the persisted queue restored them and they reappeared
in the Transfer Queue panel.
Route these clears through transferManager (like clearPending already
does) so each calls persistQueue() after mutating the store.
