_parse_network_data now returns mac, hostname, and link_status extracted
from the Redfish EthernetInterfaces/1 response (MACAddress, HostName,
LinkStatus fields confirmed present in live IOM output).
_print_results gains a second table — Interface Details (IOM | MAC | Hostname)
— between the Network Settings and Firmware Versions tables. Network Settings
table drops the redundant Origin column and adds Link Status instead.
Both _check_via_serial and _check_via_network updated to unpack and pass
the additional fields. fetch_current_config in workflow_serial.py also
updated to use the same address-parsing logic and trimmed table layout.
