Issue: Update Backend README.md

Description

The backend README.md needs to be updated to ensure it accurately reflects the current backend architecture, setup instructions, environment configuration, and API usage of the Visitor App.

Over time, several changes and improvements have been made to the backend services, but these updates are not fully documented in the repository. Updating the README.md will help developers understand the system quickly and maintain consistency across environments.
