ServeStorageAPI gains POST /api/storage/migrate (whole-namespace), POST /api/storage/migrate-app (single app), GET /api/storage/migrate/status (poll). settings.html: the greyed migrate-all span becomes a real target-select + button + shared progress panel; app_info.html gains a per-app 'Áthelyezés másik tárhelyre' control. Both poll the shared status endpoint and render Hungarian phase progress. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
