wangyu 9fb3dcb785 feat(linkage): 计划-鞍座-实绩-停机联动 + 成本管理页
后端:
- 计划录入即「准备好」,队首(最早)自动「在线」(唯一)
- 新增上卷鞍座联动引擎 line_service:移动→鞍座→(有速度/投入生产)→生产中
  →带头达2000m→生产完成并自动产生实绩、持久化运行数据
- 停机自动检测:线速度为0持续>10min 自动新增待补充停机记录,恢复后自动结束
- /plan/start=移动到鞍座, 新增 /plan/{id}/commit 投入生产, /plan/saddle/current,
  /plan/seed 批量插入(轧制力模式);后台引擎循环自动推进
- 新增成本管理:CostRecord 模型 + /cost CRUD + 9 类成本项(乳化液/盐酸/碱/电/水/蒸汽…)

前端:
- 入口跟踪重构为单个上卷鞍座工位(实时速度/带头长度进度/投入生产)+待上卷卡片+队列,
  计划列表/卡片/队列均可「移动」
- 新增成本管理页(成本项切换 + 柱+线图 + 明细表 + 时间筛选 + 新增),布局参考乳化液耗量统计
