Build me a movie rental management system with a simple admin style web app.

I want a backend that stores movies, customers, and rentals in a PostgreSQL database, with login and protected API access using JWT. The app should let me add, edit, view, and remove movies, manage customer records, and create rental and return transactions so I can see what is currently rented out and what is available. Please make the frontend a clean React app with a polished table based interface, forms, and basic navigation for the main sections.

Set it up so the backend and frontend can run separately, with environment config for the API URL, database connection, and secret key. Use sensible validation and show helpful error messages in the UI. If you need to check current docs for anything, go ahead and look them up online. Keep the design straightforward and easy to use, like a real small business rental system.
