feat: [hr] 인사관리 사원관리 Phase 1 구현

- Employee, Position 모델 생성 (tenant_user_profiles, positions 테이블)
- EmployeeService 생성 (CRUD, 통계, 필터/검색/페이지네이션)
- 뷰 컨트롤러(HR/EmployeeController) + API 컨트롤러 생성
- Blade 뷰: index(통계카드+HTMX테이블), create, edit, show, partials/table
- 라우트: web.php(/hr/employees/*), api.php(/admin/hr/employees/*)
