Tradeify247: each person sizes a little apart from everyone else

Every machine sized a like account in a like state to the same position as
every other person's, so two people's positions could match to the unit.
Each person now draws a size factor in [0.85, 1.15] per trade date, seeded
by the master's uuid for them; all of one person's accounts share it.

The factor moves the hold a DXtrade leg is sized for (hold / factor², since
size goes as 1/√hold), so the instrument pick, the dashboard's next leg and
the Firms page's reach test all see the hold the size was made for.
