feat: Enhance audit logging with client IP tracking

- Integrated client IP address retrieval in the audit logging functionality across multiple controllers, including admin, common code, department, flow, screen, and table management.
- Updated the `auditLogService` to include a new method for obtaining the client's IP address, ensuring accurate logging of user actions.
- This enhancement improves traceability and accountability by capturing the source of requests, thereby strengthening the overall logging mechanism within the application.
