Test for Common/domain/replication_queue: GetMessagesfromDLQ & AckLevel

[abhishekj720]

Why?:
Strengthening the test coverage for key components of the replication queue, specifically for retrieving messages from the DLQ and querying acknowledgment levels.

What has changed?:

Refined the GetMessagesFromDLQ test cases to validate successful message retrievals from DLQ, along with handling of read failures, ensuring the function behaves as expected in various scenarios.
Expanded the testing for GetAckLevel to cover successful acknowledgment level retrievals and to check the function's robustness against potential data retrieval issues.

How did you test it?:
unit tests with mock objects

Potential risks:
No risk involved.
