Add unit tests for OrchestrationManager with comprehensive mocking

- Implemented unit tests for the OrchestrationManager class to ensure proper functionality.
- Mocked external dependencies including Azure services and agent framework components.
- Covered various scenarios including orchestration initialization, agent creation, and event processing.
- Ensured error handling and edge cases are tested, including failures in client and manager creation.
- Verified that orchestration runs correctly with different input types and handles WebSocket errors gracefully.
