Add Description API

[mm-hsh]

This pull request introduces a new Description API endpoint, providing a self-describing service descriptor with supported profiles. It implements the API, handler, service, and domain model, and adds comprehensive unit and integration tests. Additionally, it registers the new services in dependency injection. Some test code cleanup and minor refactoring are also included.

Description API Implementation:

• Added DescriptionController with a GET endpoint at /description that returns a list of supported profiles as a service descriptor (ServiceDescriptionDto). [1] [2]
• Implemented DescriptionHandler and IDescriptionHandler to encapsulate the logic for retrieving the service descriptor. [1] [2]
• Added a mapping profile to convert the domain model (ServiceDescription) to the DTO (ServiceDescriptionDto).
• Introduced the domain model ServiceDescription and its DTO representation. [1] [2]
• Implemented DescriptionService and IDescriptionService to provide the supported profiles. [1] [2]

Dependency Injection:

• Registered the new handler and service in the application's dependency injection setup. [1] [2]

Testing:

• Added unit tests for the controller, handler, mapping profile, and service. [1] [2] [3] [4]
• Added integration tests for the Description API endpoint.

Test Code Cleanup:
