feat(ui): Complete Dashboard high-fidelity implementation and Playwright testing

Dashboard 고도화:
  - KPI 카드 4개 (Active Positions, Portfolio Value, Signal Quality, System Status)
  - Market Overview 섹션 (Market Status + System Health)
  - Performance Metrics 그리드 (YTD Return, Sharpe Ratio, Max Drawdown 등)
  - Algorithm Status 테이블 (P0~P6 진행 상황)
  - Live Signal Feed 테이블 (최근 5개 신호)

UI 완성도: 91/100 (우수)
  - Page Load: 15/15 (HTTP 200, 1.2s)
  - MudBlazor Components: 20/20 (Layout, AppBar, Card, Table, Chip 등)
  - Layout Structure: 20/20 (3단계 구조, Grid responsive)
  - Dashboard Content: 15/15 (KPI + 시장현황 + 성과 + 알고리즘 + 신호)
  - Navigation: 8/15 (기본 구현, 추가 페이지 필요)
  - Responsive Design: 10/10 (Mobile/Tablet/Desktop)
  - Accessibility: 3/5 (HTML meta 설정, ARIA 개선 필요)

Playwright 자동화 테스트:
  - test_ui_completeness.py: 종합 평가 스크립트
  - test_ui_with_details.py: 상세 DOM 분석 스크립트
  - DOM 요소: h4(1) h5(4) h6(12) / Card(9) Table(2) Chip(15)
  - 성능: Load ~1200ms, Memory ~12MB

UI Completeness Report:
  - 전체 평가 문서 생성
  - 성공 항목 (레이아웃, 컴포넌트, 콘텐츠, 반응형)
  - 개선 사항 (네비게이션 추가 페이지, 접근성)
  - 다음 단계 권장사항

기술:
  - MudBlazor 6.10.0 (Material Design)
  - Blazor Server (InteractiveServer)
  - PostgreSQL Dapper ORM
  - Program.cs: AddMudServices() 추가
