Added Phase‑1 continuation work across deep links, offline moderation queue, and admin push.

resources/js/admin/mobile/lib.
  - Admin push is end‑to‑end: new backend model/migration/service/job + API endpoints, admin runtime config, push‑aware
    service worker, and a settings toggle via useAdminPushSubscription. Notifications now auto‑refresh on push.
  - New PHP/JS tests: admin push API feature test and queue/haptics unit tests
  Added admin-specific PWA icon assets and wired them into the admin manifest, service worker, and admin shell, plus a
  new “Device & permissions” card in mobile Settings with a persistent storage action and translations.
  Details: public/manifest.json, public/admin-sw.js, resources/views/admin.blade.php, new icons in public/; new hook
  resources/js/admin/mobile/hooks/useDevicePermissions.ts, helpers/tests in resources/js/admin/mobile/lib/
  devicePermissions.ts + resources/js/admin/mobile/lib/devicePermissions.test.ts, and Settings UI updates in resources/
  js/admin/mobile/SettingsPage.tsx with copy in resources/js/admin/i18n/locales/en/management.json and resources/js/
admin/i18n/locales/de/management.json.
