feat: tkuser 통합 관리 서비스 + 전체 시스템 SSO 쿠키 인증 통합

- tkuser 서비스 신규 추가 (API + Web)
  - 사용자/권한/프로젝트/부서/작업자/작업장/설비/작업/휴가 통합 관리
  - 작업장 탭: 공장→작업장 드릴다운 네비게이션 + 구역지도 클릭 연동
  - 작업 탭: 공정(work_types)→작업(tasks) 계층 관리
  - 휴가 탭: 유형 관리 + 연차 배정(근로기준법 자동계산)
- 전 시스템 SSO 쿠키 인증으로 통합 (.technicalkorea.net 공유)
- System 2: 작업 이슈 리포트 기능 강화
- System 3: tkuser API 연동, 페이지 권한 체계 적용
- docker-compose에 tkuser-api, tkuser-web 서비스 추가
- ARCHITECTURE.md, DEPLOYMENT.md 문서 작성
