Show stage-aware + consistency-adjusted profit target on dashboards

State API now returns effectiveProfitTarget = max(stage profit target,
maxDay/consistency). When a big day forces the consistency rule, this
reflects the actual amount needed to complete the stage — not just the
base profit target.

Main dashboard and account detail page now display this instead of the
raw cfg.profitTarget.
