Build me a simple CRM web app for managing customers and their interactions.

I want a clean dashboard where I can add, edit, search, and delete customer records, and view basic details like name, email, phone, company, and notes. It should feel easy to use, with a nice frontend and a working backend so the data is saved properly instead of disappearing on refresh.

Please set it up as a full MERN app with a React frontend, a Node and Express API, and MongoDB for storage. Make sure the frontend talks to the backend correctly, and add the usual forms and list views a small business team would need. If something needs to be checked against current docs or best practices, look it up online and use the latest approach.

Keep the UI simple and professional, and make sure the project runs cleanly from start to finish.
