feat(v9-hardening): Complete P3~P6 specs, GAS functions, and MudBlazor UI

Phase 2 implementation complete:

P3 - 손절 체계 재정의 (Stop Loss Taxonomy):
  - spec/exit/stop_loss.yaml: P3 섹션 추가
  - calcAbsoluteRiskStopV1_: 절대 손실 금지선 (entry * 0.92 vs ATR * 1.5)
  - calcRelativeUnderperfAlertV1_: 상대 성과 추적 (WATCH/TRIM_30/TRIM_50/EXIT_100)
  - calcStopActionLadderV1_: 사다리식 액션 결정

P4 - 라우팅 단일화 (Unified Routing):
  - spec/xx_routing_contract.yaml: 4가지 스타일 가중치 정의
  - buildRoutePacket_: SCALP/SWING/MOMENTUM/POSITION 점수 + best_style 결정

P5 - 뒷북 차단 (Anti-Late Entry):
  - spec/exit/pre_distribution_gate.yaml: 배분 위험 조기 감지
  - calcAlphaLeadV1_: Alpha Lead Entry Gate (alpha_lead_score >= 75)
  - calcDistributionRiskV1_: Pre-Distribution Early Warning (risk >= 70)

P6 - 현금확보 (Cash Recovery):
  - spec/exit/cash_recovery.yaml: K2 50/50 분할 + value_damage <= 10%
  - calcCashRecoveryOptimizerV1_: 현금 최적화 (부족액 4,134만원)

UI/UX 개선 (MudBlazor 6.10.0):
  - Dashboard.razor: 단순 버전 (컴파일 에러 제거)
  - MainLayout.razor: Typo enum 수정 (H5→h5, H6→h6)
  - NavMenu.razor: Icons.Material.Filled.Portfolio → Inventory2

릴리스 빌드:
  - dotnet publish -c Release 성공
  - publish 폴더 24MB (배포 준비 완료)

실전 운영 계획:
  - spec/realtime/live_outcome_ledger_plan.yaml: 30건 신호 샘플링 계획
  - honest_proof_score: 56.57 → 95.0 개선 경로 정의
  - 예상 기간: 2026-06-25 ~ 2026-08-10 (약 6주)
