feat(voice): render the pointer reticle beside the voice control

PointerReticle keeps the turn's timers and tool tracking and presents
where the user pointed to the gev-pointer-reticle store, one entry per
reticle; the command dock teleports each to the body with the same
class, aria-hidden, hidden state, target and position. The voice QA
reads the card and reticle after Vue's flush, and the application guide
says leaving out the command dock leaves out the voice control and its
reticle.
