Introduced a full-featured analytics module for e-commerce business intelligence, including sales, product, customer, shipping, and review analytics, with API endpoints for dashboard and custom reports. Added VAT rate management: new VATRate model, admin interface, serializer, and API endpoints, and integrated VAT logic into Product and pricing calculations. Refactored configuration and admin code to support VAT rates, improved email notification tasks, and updated related serializers, views, and URLs for unified configuration and VAT management.
