feat: Implement smart factory log management features

- Added new API endpoints for retrieving company-specific user lists and sending immediate logs for selected users.
- Enhanced the smartFactoryLogController with functions to handle user retrieval and immediate log sending, improving operational efficiency.
- Updated adminRoutes to include routes for the new functionalities, ensuring proper access control for super admins.
- Refactored the sendSmartFactoryLog function to improve logging and error handling, providing better insights into the log transmission process.

These changes aim to enhance the smart factory log management capabilities, facilitating better user interaction and operational tracking.
