feat: add webhook notification system with Settings UI (REMOTE-03)

Webhook module with HTTP delivery, HMAC-SHA256 signing, and event
filtering. RPC handlers for get-config, configure, and test endpoints.
Settings page gains webhook configuration section with URL, secret,
event toggles, and test button.

- [x] **REMOTE-02** — Mobile-optimized remote management verified. Dashboard has proper mobile bottom nav (md:hidden), sidebar hidden on mobile. Fixed: Settings.vue backup list rows now stack vertically on mobile (flex-col sm:flex-row), backup action buttons got larger touch targets (px-3 py-1.5, flex-wrap). AppDetails.vue uninstall button enlarged (w-10 h-10). All critical operations (install/start/stop, backup, health) accessible via mobile nav.
- [ ] **REMOTE-03** — Implement remote notification system. Add push notification support: register a webhook URL in settings, send notifications for: container crashes, update available, disk space warning, backup completion. **Acceptance**: Webhook fires for configured events.
