Feature: Add database-driven shipping rates management

- Add ShippingRate model to Prisma schema with service name, base price, per-kg surcharge, estimated delivery days, and international flag - Create migration to add shipping_rates table - Update seed.ts to populate initial Royal Mail rates (domestic and international) - Refactor getRoyalMailShippingQuotes to fetch rates from database with fallback to defaults - Add /admin/shipping-rates page for managing rates - Add ShippingRatesForm component with inline editing and add/remove functionality - Add server actions for saving and deleting rates - Add "Shipping rates" link to admin navigation Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
