ghosheh33/customer-location ? reverse-engineered prompt

Build me a simple customer location app from this repo.

I want a small web app where I can save a customer’s details and their location, then view those customers in a clean interface. Please make the backend work properly, connect it to the frontend, and make sure the whole thing runs without broken parts. Use the existing backend and frontend folders, and keep the UI straightforward and easy to use.

If anything in the setup is unclear, check the current docs or look up whatever you need online. Please also clean up the project so it feels finished, with sensible defaults, working forms, and a simple way to see the saved customer locations.
