Add support for dynamic local services module

- Introduced a check in `load_service_from_path` to ensure the `local_services` module is created in `sys.modules` if it doesn't exist, facilitating proper relative and absolute imports for service plugins.
- This enhancement improves the loading mechanism for local service plugins, ensuring smoother integration and functionality.
