+/**
+ * Push Notification Configuration
+ *
+ * AUTO-CONFIGURATION:
+ * ------------------
+ * Push notifications are now auto-configured!
+ *
+ * On first server startup:
+ * 1. VAPID keys are automatically generated (requires pywebpush)
+ * 2. Keys are saved to /config/vapid_keys.json (persists across restarts)
+ * 3. Public key is served via /api/push/config
+ * 4. Client fetches config dynamically
+ *
+ * No manual configuration needed - just make sure:
+ * - pywebpush is installed: pip install pywebpush
+ * - /config directory is mounted as Docker volume (for persistence)
