Refactor Microservice with Flask-RESTX

[NBFYayI]

As a Developer I need to refactor the microservice using Flask-RESTX. So that I can provide Swagger documentation and better API management.

Details and Assumptions

• Tests should be written in Gherkin syntax.

• Ensure that existing functionality remains intact after the refactor.

  Acceptance Criteria

Given the service is refactored with Flask-RESTX 
When I access the Swagger docs 
Then I should see accurate documentation for all API endpoints.
