Implement complete e-commerce functionality with shipping and order management
Features Added: - Standard e-commerce properties (Price, Weight, shipping fields) - Order management with Create/Edit views and shipping information - ShippingRates system for weight-based shipping calculations - Comprehensive test coverage with JWT authentication tests - Sample data seeder with 5 orders demonstrating full workflow - Photo upload functionality for products - Multi-cryptocurrency payment support (BTC, XMR, USDT, etc.) Database Changes: - Added ShippingRates table - Added shipping fields to Orders (Name, Address, City, PostCode, Country) - Renamed properties to standard names (BasePrice to Price, ProductWeight to Weight) - Added UpdatedAt timestamps to models UI Improvements: - Added Create/Edit views for Orders - Added ShippingRates management UI - Updated navigation menu with Shipping option - Enhanced Order Details view with shipping information Sample Data: - 3 Categories (Electronics, Clothing, Books) - 5 Products with various prices - 5 Shipping rates (Royal Mail options) - 5 Orders in different statuses (Pending to Delivered) - 3 Crypto payments demonstrating payment flow Security: - All API endpoints secured with JWT authentication - No public endpoints - client apps must authenticate - Privacy-focused design with minimal data collection Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
