feat: Implement Phase 6 Shopping and Checkout

- Introduced authenticated shopping state and atomic checkout process without creating orders or payments. - Reused existing components from previous phases including identities, addresses, catalogues, pricing, and inventory. - Developed cart architecture to support one active cart per user with unique items per variant. - Implemented dynamic cart pricing with various precedence rules for promotions and coupons. - Created a wishlist feature that exposes only visible active products without reserving inventory. - Integrated inventory validation to ensure availability of items before adding to cart. - Developed a checkout architecture that locks the cart, revalidates pricing and shipping, and reserves inventory. - Added shipping zones, methods, and rates with configurable options for international shipping and duty/tax boundaries. - Implemented checkout snapshots to capture immutable checkout details. - Introduced idempotency for checkout requests to prevent duplicate processing. - Added functionality for coupon integration and business checkout validation. - Established permissions for managing shipping zones, methods, and rates. - Created comprehensive unit tests covering various aspects of the shopping and checkout processes. - Added cron job for handling checkout expiry reconciliation. - Created migration script to set up new database tables and constraints for carts, checkout sessions, and shipping.
