The old Refresh button disabled itself while /gallery/rescan ran; Import →
Rescan closed its dialog and showed nothing. Now a toast says the rescan
started ("Rescanning output folders…") and how it ended ("Rescan finished.
N files in M output folders.", from the scan's own total and roots, or
"Rescan could not finish. Try again."). A reopened Import dialog shows
Rescan as "Rescanning…" and aria-disabled, and ignores a press on it.
Failing before: the held-rescan browser test saw no toast and no busy
state; the dialog unit test found no "Rescanning…" button.
