feat(halpi): show device_id in status output

The device unique ID is already exposed by halpid at /values/device_id,
but the halpi CLI had no way to display it. Add it to the version block
of `halpi status` so it sits alongside hardware_version and
firmware_version. Widen the value column from 15 to 16 chars to fit the
16-char hex ID without misaligning the rest of the table.
