fix: TypeScript 타입 오류 수정 및 설정 페이지 추가

- BOMItem Omit 타입 시그니처 통일 (useTemplateManagement, SectionsTab, ItemMasterContext)
- HeadersInit → Record<string, string> 타입 변경
- Zustand useShallow 마이그레이션 (zustand/react/shallow)
- DataTable, ListPageTemplate 제네릭 타입 제약 추가
- 설정 관리 페이지 추가 (직급, 직책, 휴가정책, 근무일정, 권한)
- HR 관리 페이지 추가 (급여, 휴가)
- 단가관리 페이지 리팩토링
