Filip - Mews backend developer task (.NET)

[filipworksdev]

Hello this is the initial implementation for the backend task.

Reorganized the structure in multiple projects in src/ and tests/ to be more clean and organized.

I also added a Client and Api for frontend/backend testing for completeness.

Edit: I will be solving comments on my ticket later today for completeness👍

Edit2: I have completed copilot PR review fixes.

Edit3: I have added a docs section and a README.MD that was missing from the project
