refactor(WEB): 품목관리 경로 통합 - /items 삭제 및 /production/screen-production으로 일원화

- /items 폴더 삭제 (중복 경로 제거)
- /production/screen-production에 신버전 DynamicItemForm 기반 페이지 적용
- 구버전 ItemForm 연결 제거로 등록/수정 오류 해결
- 컴포넌트 내부 경로 참조 /items → /production/screen-production 변경
  - ItemListClient, ItemForm, ItemDetailClient, ItemDetailEdit, DynamicItemForm
