refactor(WEB): 전체 actions.ts에 공통 API 유틸 적용

- buildApiUrl / executePaginatedAction 패턴으로 전환 (40+ actions 파일)
- 직접 URLSearchParams 조립 → buildApiUrl 유틸 사용
- 수동 페이지네이션 메타 변환 → executePaginatedAction 자동 처리
- HandoverReportDocumentModal, OrderDocumentModal 개선
- 급여관리 SalaryManagement 코드 개선
- CLAUDE.md Server Action 공통 유틸 규칙 정리
