feat: 근무/출퇴근 설정 및 현장 관리 API 구현

- 근무 설정 API (GET/PUT /settings/work)
  - 근무유형, 소정근로시간, 연장근로시간, 근무요일, 출퇴근시간, 휴게시간
- 출퇴근 설정 API (GET/PUT /settings/attendance)
  - GPS 출퇴근, 허용 반경, 본사 위치 설정
- 현장 관리 API (CRUD /sites)
  - 현장 등록/수정/삭제, 활성화된 현장 목록(셀렉트박스용)
  - GPS 좌표 기반 위치 관리

마이그레이션: work_settings, attendance_settings, sites 테이블
모델: WorkSetting, AttendanceSetting, Site (BelongsToTenant, SoftDeletes)
서비스: WorkSettingService, SiteService
Swagger 문서 및 i18n 메시지 키 추가
