👾 Description of the issue

In the hiero-base module, the AccountClientImpl class implements the createAccount method, which creates a new account with an initial HBAR balance by interacting with the ProtocolLayerClient. However, this method currently lacks unit and integration tests. Scenarios such as successful account creation, invalid initial balances, 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 AccountClientImpl to include tests for the createAccount method. Use JUnit to validate positive scenarios like successful account creation and negative scenarios such as invalid HBAR balances and error handling during account creation.
