A 200-file bulk move is one long server-side copy+index chain per file, so
the old single request sat on a spinner the whole time (and got uncomfortably
close to the 120s proxy timeout). The modal now resolves the selection in
chunks of 8:
- footer switches to a progress bar with 'n moved / done / total / percent'
while running, and the header explains that files are being indexed;
- the rating pills, selection actions, grid and close button are locked
while it runs so progress can't be lost by accident;
- failures are collected with their filenames, the modal stays open for a
summary, and 'Retry failed' re-selects only the files that are still
pending; a clean run still auto-closes with a toast.
