feat: Implement live Shipping settings page

Implemented functional Shipping settings page with WooCommerce integration.

Features:
✅ Fetch shipping zones from WooCommerce API
✅ Display zones with rates in card layout
✅ Refresh button to reload data
✅ "View in WooCommerce" button for full settings
✅ Edit zone links to WooCommerce
✅ Add zone link to WooCommerce
✅ Loading states with spinner
✅ Empty state when no zones configured
✅ Internationalization (i18n) throughout
✅ Shipping tips help card

Implementation:
- Uses React Query for data fetching
- Integrates with WooCommerce shipping API
- Links to WooCommerce for detailed configuration
- Clean, modern UI matching Payments page
- Responsive design

API Endpoint:
- GET /settings/shipping/zones

Note: Full CRUD operations handled in WooCommerce for now.
Future: Add inline editing capabilities.
