fix(scriptc): Capture the BMC USB service log to a file, not the console
journalctl now runs with -o short-iso into log/bmc_usb_net.log and is copied into the job directory with the other monitor logs. rm -f first so the file covers this run only, and the ISO timestamps line up with mgmt_ping.log and nfc_poll.log for cross-referencing. The cost, recorded rather than glossed over: it is no longer echoed to the console, so the USB copy is the only copy. That cp return value is not checked - the same shape as the nfc_polling.log filename bug, which failed silently and was only noticed back at the desk with a job archive missing a file. Folded into V1.1.6 rather than bumping: the tag has not moved on and this is the same delivery.

* **`READ_VIN` and `READ_IIN` are not in the datasheet's coefficient table.** They are decoded here with the voltage and current coefficients — consistent with a ~50 V input, but not stated by the datasheet.

* **The BMC USB service log only exists on the USB stick.** It is not in the master console log any more.
