fix: Update test configurations and improve Home Assistant route tests

### Summary of Changes
- Added `--asyncio-mode=auto` to `pytest.ini` for better async test handling.
- Corrected patch decorators in `test_general_routes.py` and `test_home_assistant_routes.py` to reference the correct services.
- Enhanced test assertions in `test_home_assistant_routes.py` to verify service availability and response codes.
- Improved clarity and maintainability of test code by applying clean code principles.

### Expected Results
- Improved test execution for asynchronous code and better organization of test cases.
- Enhanced reliability of Home Assistant route tests, ensuring accurate service behavior verification.
