加强发货提交可靠性并统一契约口径

- 发货提交记录阶段推进与失败分类，失败不再清空 result_data
- 超时巡检区分已提交上游与提交中断两类卡单，避免误判
- 已提交上游的失败订单禁止自动重发，防止重复发货
- ship_attempts 仅在 claim 时计数，失败阶段只记录分类信息
- CanFulfill 对已提交上游的失败单返回不可发货
- 删除预留的 pending 订单状态，统一订单状态模型
- 契约改名：order.fulfillment.updated -> order.shipping.updated，fulfillment:read -> shipping:read
- 文档修正 scope 为或关系
