구매관리 입고관리 입고등록 + 입고일별 마감정보입력 + 매입마감

- backend purchaseInboundService 신설 — getInboundFormInit / saveInboundForm
  (arrival_plan UPSERT 트랜잭션) / saveDeadlineInfo (8필드 일괄 UPDATE) /
  closeArrival (이미 마감된 건 차단) + listWarehouseOptions / listAcctCodeOptions
- backend routes — GET /inbound-form/:pomObjid / POST /inbound-form/save /
  POST /arrival/deadline / POST /arrival/close + 옵션 2개
- InboundFormDialog 신설 — wace deliveryAcceptanceFormPopUp_new.jsp 1:1
  (좌 발주품목 read-only + 우 차수별 입고입력 + 미입고 일괄적용)
- DeadlineInfoDialog 신설 — wace swal 모달 1:1 (8필드 일괄, 단건 시 prefill)
- inbound 페이지 입고등록 / inbound-by-date 마감정보입력+매입마감 연결
- 입고등록 master SELECT 함정 수정 — RPS 에 POM.delivery_status 없어 reception_status fallback
- DataGrid 다중 frozen 누적 left 계산 인프라 추가 (frozenLeftPx props 보강)
  — shadcn Table 기반이라 진짜 column pinning 불가 (자연 위치 도달 후 sticky),
    입고 3페이지의 frozen 부여는 일단 제거. 진짜 pinning 은 별도 작업
