🤖 Improve Error Handling in Checkout Process

[sentry-autofix]

👋 Hi there! This PR was automatically generated 🤖

Fixes REACT-46F

The current checkout process in Checkout.js does not properly handle server-side exceptions in a way that alerts the user to the exact problem. The action plan involves enhancing the error handling by providing more descriptive error messages based on the HTTP status code returned by the server, and ensuring any server-side exceptions are caught and handled gracefully.

The steps that were performed:

1. Add descriptive error messages
2. Log exceptions in server-side checkout
3. Update error navigation
