Surfaces three events without a full notification center:
- service worker (public/sw.js) gains push + notificationclick handlers
(RTL, focuses an existing tab or opens the target URL).
- usePushNotifications hook: permission + VAPID subscribe/unsubscribe
against the backend push endpoints.
- opt-in UI both ways: a one-time dismissible post-login banner
(PushPermissionBanner, rendered in MyLayout) and a permanent toggle
(PushSettingToggle) on buyer profile settings and seller store settings.
- useBadgeCounts polls /api/notif/v1/badges/; small red badges on the
bottom-nav profile icon (chat + order updates), the profile sidebar
(پیامها / سفارشها) and the seller dashboard sidebar. Visiting orders
clears its badge.
Degrades gracefully: if the backend endpoints are absent the counts fall
back to zero and nothing throws.
