Issue: sometimes it happens that an ul failure occurs in the handover
pipeline, UE reconnects with different UE ID and fetch_du_by_ue_id fails.
- Modified fetch_du_by_ue_id in telnetsrv_ci.c to automatically find
the connected UE when no UE ID is provided, similar to other
telnet commands like rrc_gNB_trigger_f1_ho
- Updated test cases in container_sa_f1_ho_b210_quectel.xml to use
the improved command without hardcoded UE ID parameter
- This makes the command more robust and easier to use in CI tests
