fix: 코드리뷰 즉시수정 4건 + 모니터링 실제 API 연동

[1] NavMenu.razor — 하드코딩 'v2.1.0-Release' 버전 블록 완전 제거
    버전 표시는 MainLayout의 version.json 단일 소스로 통일

[2] MainLayout.razor — 로그아웃 URL 버그 수정
    /Account/Login?handler=Logout → /Account/Login
    (Razor Pages GET 핸들러는 쿼리스트링 ?handler=로 호출되지 않음)

[3] Dashboard.razor — AllowAnonymous 제거, debug 코드 정리
    - @attribute [AllowAnonymous] 삭제
    - DEBUG MARKER div 삭제
    - TEMPORARY 주석·Console.WriteLine 정리
    - 미인증 시 /Account/Login 리다이렉트 활성화

[4] DataCollectionMonitoring.razor — 전체 하드코딩 더미 데이터 제거
    - 'RUN-2026-07-05-002 진행중 30분+' 등 모든 더미 데이터 제거
    - /api/collection/runs + /api/collection/state 실제 API 연동
    - 로딩 스피너, 새로고침 버튼, 실제 상태 카운트 구현
