Build a payment controller with rest controller annotations and api path /api/payments, expose post /pay to create payment intents, and include update payments with validation and logs.

Set up the front end by installing node and npm and creating a React app. Add dependencies such as stripe, Axios, react-router-dom, react date picker, and crypto-js.
