Account calendar: reach probabilities, 2-payout horizon, outline cells, same-day payouts, real drawdown floors

- projectPerfectPath books each cycle's payout ON its final trading day
  and anchors ruin probabilities to the platform's real liquidation floor
  (Tradovate auto-liq) when reported, else the configured trailing
  drawdown with the maxLoss/$2,000 fallback
- Account calendar shows the cumulative reach % on every projected day,
  caps the projection at two payouts ahead, and renders potential days
  as dashed outlines instead of shaded cells
