fix(WEB): 수주 등록/수정 옵션 필드 저장 및 담당자 표시 문제 해결

- FormRequest에 options 필드 validation 추가 (StoreOrderRequest, UpdateOrderRequest)
  - shipping_cost_code, receiver, receiver_contact, shipping_address 등
- OrderService.show()에서 client 로드 시 manager_name 필드 추가
- 수주확정/생산지시 되돌리기 기능 추가 (revertOrderConfirmation, revertProductionOrder)
- 견적 calculation_inputs 포함하여 로드
