falmiabdi/Hachalu-protocols ? reverse-engineered prompt

Build out this project so the client and server work together as a complete app that I can run locally and with Docker.

I want the main pages and API to be wired up cleanly, the environment variables to match the example file, and the endpoints to behave the way the docs and Postman collection suggest. Make sure the app starts without manual fixes, and that the important flows can be tested end to end. If there are any broken links, placeholder URLs, or old values, clean them up. Also make sure the Docker setup and deployment config are working, and update anything needed so the project is easy to run and verify. Use the existing testing guides if they help, and look up current docs online if you need to.
