Vest: the payout projection runs on Vest's day, and stages count each payout

projectPerfectPath takes the raw trade date (default: the Central one):
the reporter passes its tradeDateFor day and the account page the one
/api/state now gives each account. From 5 PM CT to 20:00 ET it took
tomorrow as today while every input was Vest's, so the day's claim moved
a day late, the next day's stage-1 payout dropped, and an open Vest-day
row counted twice.

Without same-day stages, the stage comes from the client's payout list
(payoutDays, one per payout) when it has read one, not the negative fund
rows: Vest books a day's two claims as one row, so the engine, claimDue,
the stage label and the projection stayed a stage behind the report.
StageInputs.payouts carries the count; a client with no list counts rows
as before.
