Vest: no leg opens past 8 PM ET until a sync has read the new day

The engine's Vest day now turns with the client's numbers, at the first
sync after the reset. A leg opened between 8 PM ET and that sync would be
planned and counted on the day that ended, so both the pick and the open
wait for it. The claim log's "stage N next" counts payouts the way the
engine picks its stage.
