I finished the remaining reliability, sharing, performance, and polish items across the admin

app.
  What’s done
    locales/en/mobile.json and resources/js/admin/i18n/locales/de/mobile.json.
  - Error recovery CTAs on Photos, Notifications, Tasks, and QR screens so users can retry without a full reload in    resources/js/admin/mobile/EventPhotosPage.tsx, resources/js/admin/mobile/NotificationsPage.tsx, resources/js/admin/
    mobile/EventTasksPage.tsx, resources/js/admin/mobile/QrPrintPage.tsx.
  - QR share uses native share sheet when available, with clipboard fallback in resources/js/admin/mobile/
    QrPrintPage.tsx.
  - Lazy‑loaded photo grid thumbnails for better performance in resources/js/admin/mobile/EventPhotosPage.tsx.
  - New helper + tests for queue count logic in resources/js/admin/mobile/lib/queueStatus.ts and resources/js/admin/
    mobile/lib/queueStatus.test.ts.
