Vest: a claim counts on the fresh day only once Vest dates it there, and a day's second cycle gets its own key

A claim's stage time is now taken before the request goes out (sentAt):
Vest dates it no earlier, so a claim answered just after 20:00 ET no longer
puts the fresh Vest day on stage 2 before the history read shows its
WITHDRAW. One Vest dates after the turn reads as the day before until then,
the cautious way round. Claims saved without it count from their answer.

Completions count one per payout on both paths (completionPlace): the
catch-up's stage no longer counts a Vest day's two claims as one, and a
cycle a day's second claim started carries cycleSeq, so it can be told from
that day's first. The master ignores it until it keys on it; old masters and
old instances are unchanged.

bookHistory's claim bookkeeping (WITHDRAWs, lapse, fund rows, the balance
the books check expects) is now the pure readClaims, tested on the case
that held an account for good: a claim that never went in, read an hour on.
