feat(dialog): 상세 팝업 SuperportDetailDialog 통합

- SuperportDetailDialog 위젯과 showSuperportDetailDialog 헬퍼를 추가하고 metadata/섹션 패턴을 표준화

- 결재/재고/마스터 각 상세 다이얼로그를 dialogs 디렉터리에 신설하고 기존 페이지를 신규 팝업으로 전환

- SuperportTable 행 선택과 우편번호 검색 다이얼로그 onRowTap 보정을 통해 헤더 오프셋 버그를 제거

- 상세 다이얼로그 및 트랜잭션/상세 뷰 전용 위젯 테스트와 tester_extensions 유틸을 추가하여 회귀를 방지

- detail_dialog_unification_plan.md로 작업 배경과 필드 통합 계획을 문서화
