👾 Description of the issue

In the hiero-base module, the ProtocolLayerClientImpl class implements the executeFileDeleteTransaction method, which deletes a file by interacting with the Hedera SDK. However, this method currently lacks unit and integration tests. Scenarios such as successful file deletion, invalid file IDs, and exception handling (e.g., HieroException) are untested, leaving this functionality vulnerable to potential issues.

Suggested solution

Create a new test class or extend the existing test suite for ProtocolLayerClientImpl to include tests for the executeFileDeleteTransaction method. Use JUnit to validate positive scenarios like successful file deletion and negative scenarios such as invalid file IDs and error handling during file deletion.
