refactor(system3): 프로젝트/사용자/일일공수 관리 기능 제거

tkuser에서 프로젝트/사용자를 통합 관리하므로 TKQC에서 불필요한 기능 제거:
- 프로젝트 관리: POST/PUT/DELETE API 및 페이지 삭제 (GET 유지)
- 사용자 관리: CRUD API 및 admin.html 삭제 (login/me/change-password 유지)
- 일일 공수: daily_work.py, daily-work.html 삭제, reports.py에서 DailyWork 참조 제거
- 디버그 페이지 4개 삭제 (check-projects, sync-projects, test_api, mobile-fix)
- 네비게이션/권한/키보드 단축키에서 제거된 메뉴 정리
- tkuser permissionModel.js에서 daily_work, projects_manage 키 제거
