Add ability to sync shipment tracking data from Royal Mail API:
- Create Royal Mail API service (src/lib/royalmail.ts) to fetch tracking status
- Add sync-tracking endpoint to pull latest status from Royal Mail
- Create SyncRoyalMailButton component for admin panel
- Add 'Sync from Royal Mail' button on order detail page
- Auto-update order status based on Royal Mail tracking status
Admin workflow:
1. Create shipping label in Royal Mail Click & Drop
2. Copy tracking number into tracking form
3. Click 'Sync from Royal Mail' to fetch and update status
4. System maps Royal Mail status to our order status (SHIPPED, DELIVERED, etc)
Uses Royal Mail's public tracking API - no special credentials required.
Supports manual label creation workflow (hybrid approach).
