Vest: no leg opens into a market close, and accounts plan on Vest's day

Market close: a Vest entry now needs its symbol's market to stay open
for RESET_CLEAR_HOLDS holds of the leg (clearsClose), the clearance the
8 PM ET reset already gets: at the target hold, and at the leg's sized
hold when a leverage cap stretches it. That covers the weekly close and
the daily maintenance hour as Vest's market-hours periods list them.
Before a closure that runs past an 8 PM ET reset (the weekend, a
holiday: longClosure), the bot's own legs still open in the last 5
minutes are closed at market, loudly; a position the bot didn't open is
named in the log and left alone.

Vest's day: Vest accounts are planned, and their legs and entries
counted, on Vest's day (20:00 ET) instead of the Central date
(tradeDateFor, PlatformClient.tradeDate). Between 5 PM CT and the reset
the Central date counted the open Vest day as a prior day and as today's
realized P&L both ($3,000 to go, $800 made: $2,050 left, not $1,900) and
started the leg count over. Other platforms keep the Central date.
