Changing Normal/180/bi over a remote connection reverted to the old pattern
after ~4s: the fixed 4s optimistic window expired while the motors were still
flipping the elements, and the lagging remote status poll then overrode the UI.
Hold the commanded direction while the motors are moving, then a short grace
window after they stop for the confirmation poll to land (SteppIR already used
a generous 45s hold, which is why only Ultrabeam-remote hit this).
