dtnhan205/reseller ? reverse-engineered prompt

Build me a simple reseller web app with a frontend and backend.

I want a clean app where people can view seller or reseller listings, see details for each one, and maybe add or update entries from an admin style screen. There’s already a backend and frontend in this repo, so please wire them together into something usable and polished. Use the seller list data in the project if it helps, and make the app easy to run locally.

Please make the UI straightforward and responsive, with a nice list view, basic search or filtering if it fits naturally, and clear empty and loading states. On the backend, set up the endpoints the frontend needs and keep the data flow simple. If you need current setup details, look up the latest docs online and follow best practices.

Also make sure the app is ready to be deployed behind NGINX, since there’s a config note in the repo.
