Improvements for optimizing Checkout V2 Cart performance

We are excited to announce several performance improvements to the Checkout V2 Cart page UI. These technical changes do not impact any existing features but significantly improve how quickly the cart page loads and gets updated:

• Transitioned to GraphQL queries (activeCart) instead of REST API (preview API) to fetch details such as product, edition, and other pricing plan related information in checkout.
• Improved how relevant API data is processed. Previously, the Cart page waited for all API responses before loading. Now, the UI displays specific details as soon as API data is received. For example, if the product details are available first, they are displayed immediately, with additional information such as pricing and discounts displayed as and when they become available.

These enhancements will be enabled by default and will be available to everyone using out of the box Checkout UI features.
