Freeze hiders (pose + transform) during the resolution phase

While a match is in the resolution sub-phase, hiders that have not
been found hold their current pose and position: the pose graph is
frozen (mixer speed 0, current frame re-asserted) and owner input is
disabled while gravity/grounding keep them planted.
