fix: TypedDict compatibility for Python 3.11 and remove unused imports

- Use typing_extensions.TypedDict instead of typing.TypedDict for Python < 3.12 compatibility
- Remove unused pytest import from test_config.py
- Remove unused sys import from test_factory.py
- Fixes Pydantic error: 'Please use typing_extensions.TypedDict instead of typing.TypedDict on Python < 3.12'
