feat(inventory): 재고 현황 요약/상세 플로우를 릴리스

- lib/features/inventory/summary 계층과 warehouse select 위젯을 추가해 목록/상세, 자동 새로고침, 필터, 상세 시트를 구현

- PermissionBootstrapper, scope 파서, 라우트 가드로 inventory.view 기반 권한 부여와 메뉴 노출을 통합(lib/core, lib/main.dart 등)

- Inventory Summary API/QA/Audit 문서와 PR 템플릿, CHANGELOG를 신규 스펙과 검증 커맨드로 업데이트

- DTO 직렬화 의존성을 추가하고 Golden·Widget·단위 테스트를 작성했으며 flutter analyze / flutter test --coverage를 통과
