fix: simplify pytest configuration to resolve CI issues

- Created pytest.ini with minimal configuration
- Removed pytest config from pyproject.toml to avoid conflicts
- Set asyncio_mode=auto to prevent strict mode issues
- Removed unnecessary integration conftest.py
- Markers are already defined and tests are properly marked
