[Server] Imprement logs endpoint that return log list

[Rwatana]

Issue Number

46

Implementation Summary

This pull request implements the presenter layer for the /logs endpoint. The presenter layer formats the data from the use case layer before sending it as a response. Key changes include:

• Creation of a Presenter interface and its implementation.
• Integration of the presenter layer into the HttpLogHandler for the /logs endpoint.
• Updated response handling to ensure properly formatted output, including handling empty logs gracefully.
• Addition of unit tests to validate the presenter layer's behavior.

Scope of Impact

• Execution Timing: This feature will be executed whenever a client makes a request to the /logs endpoint.
• Value Changes: The /logs endpoint will return responses processed by the presenter layer, ensuring consistent and properly formatted output.

Particular Points to Check

• Ensure the presenter layer integration does not break existing functionality.
• Verify that the changes do not inadvertently impact other endpoints or parts of the application.
• Validate the handling of edge cases such as empty log results and unexpected errors.
