The k=2..8 alignment steps always rotated via a halfway "approach" angle before the 45 deg target, to let the operator watch the sample sweep through in live view. That's only useful when keep_shutter_open is True; with the shutter closed nobody sees the intermediate move, so just rotate straight to the target angle in that case. Also bump the OMNY/FlOMNI post-fshopen() freeze-frame delay in update_frame() from 0.5s to 1s to match LamNI's, for consistent behavior between the two plugins.
