feat(ttl): Set fan speed in Script A, archive job logs to USB in C

config.ttl gains FAN_SPEED (30). Script A rebinds the two max31790
controllers (18-0020, 25-0020) and applies the speed with
fan-speed-control.sh, answering its confirmation prompt, so a run starts
from a known thermal state rather than whatever the last test left.

Script A also clears /host/hw-eval/current/jobs before the run, and
Script C copies that directory to /mnt/usb/jobs-<date>_<time> so the
bgctl job logs leave the DUT with the run they belong to.

Fix: 25-0020 was bound twice in a row -- the second bind can only fail,
since the driver is already attached. Removed; the two controllers now
have a matching unbind/sleep/bind each.

Script A -> V1.0.7, history covering the config.ttl and Script C changes
as well.

Docs: fan control and the job-log archive added to Tech Stack, Key
Features and Data Flow; the config.ttl example refreshed with FAN_SPEED
and the SWB_UNIT flags. Three risks recorded in Future Extensions --
`rm` without -r cannot clear the job subdirectories that Script C copies
with -r, the fan confirmation wait has no timeout and would hang
silently if the prompt ever changes, and /mnt/usb is never checked for
being mounted.
