- Replace the browser confirm() with a generic #confirmationModal
(template + ModalManager registration + showConfirmationModal() helper
in modalUtils.js, promise-based, danger-styled confirm button).
- Show the loadingManager overlay while the restore request is in flight;
.json restores re-download from CivitAI and the wait previously looked
like a dead click. The overlay hides in a finally block.
