Simplify Mode A to compare equityProfit against profitTarget

Previously Mode A computed effective target = profitTarget - (priorProfit
+ totalWithdrawals), which produced inflated targets after withdrawals.

Since computeDailyTarget now uses equityProfit (amount - accountSize)
directly, Mode A just needs to return the base profitTarget unchanged.
The equity-based comparison naturally handles 'get back to same target
above accountSize' semantics.
