Subject: [PATCH] =?UTF-8?q?fix(db=20011):=20momo=5Forder=5Fitems.item=5Fob?=

증상: 거래명세표에서 [+ 택배/용차 추가] 클릭 시
  null value in column "item_objid" of relation "momo_order_items" violates not-null constraint

원인: 001_momo_init.sql 에서 item_objid 가 TEXT NOT NULL 로 정의됨.
       택배/용차 라인(kind=DELIVERY/CHARTER)은 품목이 아니라 가상 부가 라인이라 NULL 이 정상.

해결: ALTER ... DROP NOT NULL. ITEM 라인은 어차피 코드 레벨에서 항상 값을 넣고 있어 무영향.
