refactor: optimise test_autoagents.py for clarity and consistency

- Updated tool configurations to use string names instead of Mock objects for better clarity.
- Simplified the test for custom API key and base URL, ensuring parameters are stored correctly.
- Enhanced comments to improve understanding of the test setup and expected behaviour.

These changes improve the readability and maintainability of the test suite while ensuring accurate validation of configurations.
