The SteppIR client logged commands it sent but never the status frames it read
back, so a misread motor-status byte — which drives the app's "block TX while
the antenna is moving" interlock on a FlexRadio — was invisible. Log the raw
11-byte frame plus the decoded freq/dir/moving and the motor (buf[6]) and
direction (buf[7]) bytes, but only when the frame changes, to keep the 2 s poll
from flooding the log. Purely diagnostic; no behaviour change.
