fix(实例路由): 转发失败不再伪装成「任务不存活」

归属节点滚动重启时跨节点转发会连接失败，原来返回 ApiResponse.fail(40903) —— HTTP 200 + data:null。客户端把「拿不到数据」解析成 alive=false，于是把健康的长任务主动停掉（2026-09-18 任务 28616：跑到 66/253 被自杀，只跑到第 2/6 页）。改为 503 + 空 body：新客户端按状态码判未知继续跑；老客户端因 body 不是 JSON、 resp.json() 抛异常也落到未知——两边都不会再把未知当成死。顺带让这类故障在 HTTP 指标里可见（原先记成 200，滚动重启期间丢了多少心跳监控完全看不到）。
feat(上架): 店铺互斥改为按(设备,店铺)，同店可在不同客户端并行跑不同国家
