mousaabdelbasset/ai_cv_task — reverse-engineered prompt

Build out this C# API project for the AI CV task so it actually works end to end. Please inspect the existing folders and code first, then fill in whatever is missing rather than starting over.

I want a simple backend where someone can send a CV related AI request, have the app validate it, process it through the existing core or helper logic, and return a clean structured response. Add sensible API endpoints, request and response models, error handling, logging, and configuration through the appsettings files. If something fails, the response should be understandable and the logs should make it easy to debug.

Keep the code clean and organized using the current Api, core, Dtos, Helper, and Infrastructure structure. Make it easy to run locally, include a few sample requests in the existing http file if useful, and look up current docs online if you need to.
