Fix stop/target ordering, P&L wiring, dynamic targets, confluence wiring

- Move SetStopLoss/SetProfitTarget before EnterLong/EnterShort in
  SubmitOrderToNT8(). NT8 requires stop/target pre-registered to the
  signal name before entry fires — calling after caused silent fallback
  to strategy defaults in backtest, nullifying all dynamic target scaling.
  Add [dynamic] tag to SUBMIT log line for observability.

- Wire OnPositionUpdate() in NT8StrategyBase to call
  _riskManager.OnPnLUpdate() and PortfolioRiskManager.ReportPnL() on
  every position change. Daily loss limit checks were evaluating against
   PnL permanently — safety net now live.

- Fix BasicRiskManager.CheckEmergencyConditions() hardcoded 1000 limit.
  Add dailyLossLimit constructor overload; emergency halt now fires at
  90% of the configured DailyLossLimit, not a hardcoded .

- Add AVWAP slope hard veto in SimpleORBStrategy.OnBar(). Trend=0.00
  (AVWAP working against trade direction) can no longer pass grade
  filter. Pre-scoring veto prevents high gap/volume scores from masking
  a directionally broken setup.

- Raise default MinTradeGrade from 4 (B) to 5 (A) in both
  SimpleORBStrategy and SimpleORBNT8 defaults.

- Scale TargetTicks dynamically in CreateIntent() based on ORB/ATR
  ratio (0.75x-1.75x of base target). Tight ORBs get extended targets;
  wide ORBs get tightened. Hard floor at stopTicks+4.

- Add NarrowRange, OrbRangeVsAtr, GapDirectionAlignment,
  BreakoutVolumeStrength, PriorDayCloseStrength default weights in
  ConfluenceScorer constructor. All 10 factors now registered.

- Fix session_open_price tracking for GapDirectionAlignment factor.
  TodayOpen in DailyBarContext now reflects first RTH bar open, not
  the breakout bar open.

- Log all 10 factor scores at signal acceptance for observability.
