- nuget.config with Soroush Nexus + Liara mirrors (nuget.org filtered); added WebPush 1.0.12
- PushNotifier: VAPID send to a user's subscriptions, prunes dead (404/410); config from AppSetting
- NotificationService fans out a Web Push to matched users' subscribed browsers after creating in-app notifications (best-effort; no-op until admin enables push + sets VAPID)
- Build verified through the mirrors; app boots with PushNotifier wired
