feat(menu-permissions): 메뉴 API 연동으로 사이드바 권한 정비

- .env.development.example과 lib/core/config/environment.dart, lib/core/permissions/permission_manager.dart에서 PERMISSION__ 폴백을 view 전용으로 좁히고 기본 정책을 명시적으로 거부하도록 재정비했다

- lib/core/navigation/*, lib/core/routing/app_router.dart, lib/widgets/app_shell.dart, lib/main.dart에서 메뉴 매니페스트·카탈로그를 도입해 /menus 응답을 캐싱하고 라우터·사이드바·Breadcrumb가 동일 menu_code/route_path를 쓰도록 리팩터링했다

- lib/core/permissions/permission_resources.dart와 그룹 권한/메뉴 마스터 모듈을 menu_code 기반 CRUD 및 Catalog 경로 정합성 검사로 전환하고 PermissionSynchronizer·PermissionBootstrapper를 확장했다

- test/helpers/test_permissions.dart, test/widgets/app_shell_test.dart 등 신규 구조를 반영하는 테스트·골든과 doc/frontend_menu_permission_tasks.md 문서를 보강했다
