fix(motor-antenna): don't inhibit TX on a band the antenna doesn't cover

The follow filter correctly leaves the antenna put on an un-ticked band, but the
TX-inhibit loop ran independently: it gagged FlexRadio transmit whenever the
antenna reported "moving" (a stray polled Moving flag, or a move finishing from
the previous band), even on a band OpsLog was deliberately not managing. An
operator working 15 m on another antenna had their FT8 cut mid-transmission by
an "antenna moving" interlock.

motorTXInhibitLoop now takes the covered-band set and forces moving=false when
the current rig band isn't in it — un-ticking a band means hands off entirely:
no tune AND no inhibit. Also correct the RCU-01 references to RCU-06 (the actual
controller behind the short 11-byte status frame).
