Feature: Add admin notification system

- Create AdminNotifications server component to fetch notification counts
- Add AdminNotificationsBadge client component to display notifications
- Show badge with total count next to Admin menu in header
- Display breakdown tooltip: pending orders, design approvals, photo requests
- Graceful error handling with fallback to zero notifications
- Integrate into Header component for all pages

Also recreate missing AddressFormSection and OlderOrders components
from previous work that weren't being tracked.
