feat: 회원가입 시 기본 메뉴 자동 생성 및 권한 설정

- MenuBootstrapService 생성: 새 테넌트를 위한 기본 메뉴 9개 자동 생성
  - 대시보드
  - 기초정보관리 (제품/거래처/BOM 관리)
  - 시스템 관리 (사용자/권한/부서 관리)
- RegisterService 수정: 메뉴 생성 후 권한 자동 설정
  - 생성된 메뉴에 대한 권한(menu.{id}) 자동 생성
  - system_manager 역할에 모든 메뉴 권한 할당
- 기존 테이블 구조에 맞게 구현 (code, route_name, depth, description 컬럼 미사용)
- message.registered 수정: '회원가입 처리'로 변경 (에러 메시지 개선)
