Follow SOLID

[yeshamavani]

Describe the bug Remove the logic from the repositories and move it to a separate service. Also add the test cases wherever necessary.

eg :- https://github.com/sourcefuse/loopback4-microservice-catalog/blob/master/services/authentication-service/src/repositories/user.repository.ts

To Reproduce Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior We should follow SOLID and repositories should not have business logic within them.
