ci: add MySQL/MinIO services to GitHub Actions workflow

- Use MySQL service container for integration tests
- Start MinIO manually (requires server command)
- Set environment variables for external container mode
- Add separate unit-tests job for faster feedback
- Test against Python 3.10-3.13 matrix
