+ * useCartSync - 장바구니 DB 동기화 훅
+ *
+ * DB(cart_items 테이블) <-> 로컬 상태를 동기화하고 변경사항(dirty)을 감지한다.
+ *
+ * 동작 방식:
+ * 1. 마운트 시 DB에서 해당 screen_id + user_id의 장바구니를 로드
+ * 2. addItem/removeItem/updateItem은 로컬 상태만 변경 (DB 미반영, dirty 상태)
+ * 3. saveToDb 호출 시 로컬 상태를 DB에 일괄 반영 (추가/수정/삭제)
+ * 4. isDirty = 로컬 상태와 DB 마지막 로드 상태의 차이 존재 여부
+ *
+ * 사용 예시:
+ * ```typescript
+ * const cart = useCartSync("SCR-001", "item_info");
+ *
+ * // 품목 추가 (로컬만, DB 미반영)
+ * cart.addItem({ row, quantity: 10 }, "D1710008");
+ *
+ * // DB 저장 (pop-icon 확인 모달에서 호출)
+ * await cart.saveToDb();
