TopstepX: look back 90 days for trade history, not 27

A first funds check can only explain an account's balance with the trades
the history window returns. P&L older than that is booked as a deposit,
which the consistency math leaves out: an Express account whose only
earlier trade was 64 days back read $5,071 short of its 40% rule instead
of $1,542, and aimed tonight's leg at its best day. Tradovate is unchanged.
