US03 - Set Up and Run Backend Skeleton Application

[RamirezJM]

As a Backend Developer
I need to configure and run the initial skeleton structure of the backend application
So that I can verify the basic project architecture, dependencies, and environment configurations are working properly.

Details and Assumptions

• The skeleton uses Node.js and Express.
• Proper environment variables (like ports and DB URIs) must be verified during this run.

Acceptance Criteria

Given the backend repository skeleton is cloned locally
When I install dependencies and run the start script
Then the server should boot up successfully and listen on the designated port without errors
