New RiskMetricsCalculator (pure) derives max drawdown (USD), daily-PnL volatility and longest losing streak from the trader's TraderDailySnapshot equity curve; the PnL engine computes them each recalc and stores them on TraderAnalytics (+ computed ReturnOverMaxDrawdown, Calmar-like). Two traders with identical final PnL but a smoother path are very differently copyable — this captures that. Exposed on TraderDetailDto. Migration AddRiskAdjustedMetrics. +5 unit tests (63 total, 1 skip). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
