PESYJE V13.4 — PWA ADVANCED PRO

Adds to V13.3:
- Advanced PRO section in Admin
- Push notification permission + subscription foundation
- Local PWA notification test
- Service Worker push event + notification click handling
- App Badging API controls
- Background Sync for queued telemetry
- Offline/runtime cache policy controls
- Runtime cache size limit
- Update policies: prompt / immediate / manual
- PWA Analytics database
- Install analytics
- Standalone launch analytics
- Offline/online analytics
- Service Worker install/activate/cache logs
- Push subscription table
- Latest PWA/SW events in Admin
- Device-level Clear Cache controls

IMPORTANT:
Remote server-to-device Web Push sending requires a VAPID key pair and a Web Push sender
(e.g. minishlink/web-push or equivalent). V13.4 stores browser subscriptions and includes
the full service-worker receiver, but does not install an external Composer package automatically.
The local notification test works without that dependency.

INSTALL:
cd /home/n377435/pesyje
php artisan migrate --path=database/migrations/2026_08_11_010500_create_pwa_advanced_tables.php --force
php artisan optimize:clear

Then:
Admin → PWA / Aplikacioni → Avancuar PRO → Ruaj PWA

Migration required: YES.
