feat(WEB): 리스트 페이지 UI 레이아웃 표준화

- 공통 레이아웃 패턴 적용: [달력] → [프리셋] → [검색창] → [버튼들]
- beforeTableContent → headerActions + createButton 마이그레이션
- DateRangeSelector extraActions prop 활용하여 검색창 통합
- PricingListClient 테이블 행 클릭 → 상세 이동 기능 추가
- 회계 관련 페이지 (입금/출금/매입/매출/어음/카드/예상지출 등) 정리
- 건설 관련 페이지 검색 영역 정리
- 부모 메뉴 리다이렉트 컴포넌트 추가
