fix: 슬랫 작업일지 데이터 파이프라인 구축

- OrderService.createFromQuote: BOM 결과에서 slat_info(조인트바/방화유리 수량) 추출하여 OrderNode.options에 저장
- OrderService.createWorkOrders: nodeOptions에 slat_info 없을 때 bom_result에서 fallback 추출
- OrderService.syncFromQuote: 동일하게 slat_info 추출 추가
- WorkOrderService: salesOrder eager loading에 client_contact, options 추가
