fix: 견적→수주 변환 시 담당자 정보 누락 수정

- Order::createFromQuote() 잘못된 필드명 수정 (contact_person→contact, delivery_date→completion_date)
- 견적 담당자(manager)를 orders.options.manager_name에 저장
- StoreOrderRequest/UpdateOrderRequest에 options.manager_name 유효성 검증 추가
- WorkOrderService show()에서 salesOrder.options 컬럼 포함하여 담당자 표시
