M6(4/n): 工作台五要素齐活 —— 审批 / 消息 / 纪要 / 汇报

四个 desk-* feature 自 workbench 原型 ModuleWorkspace.tsx 平移(jc-* 类名原样),
共用件落 shared/desk/module-kit;mock 数据换成服务端投影:
  · desk-approval:审批点卡到审批人工位;依据快照、驳回走向(声明式)、驳回必附意见
  · desk-message:通知 + 跨任务征答**就地作答**;卡面表单由 card.ts schema 驱动,
    与后端回传校验同 schema;跨人卡不占任务清单,不开放任务对话流
  · desk-minute:纪要维护 + 决议登记起单;正文可续、决议只增
  · desk-report:四周期草案 + 度量八指标 + 确认即提交
左轨角标常驻(待批 / 未读),责任面要一眼看见什么在等我。

修一个真 bug:process.start 从不校验流程包的 callInterface,
先插工作流再由 task.start 撞活动契约 —— 失败就留下一条永远推不动的在途单。
改为**先校验后建单**(CallInterfaceViolationError),一条工作流都不留;
路由回 400 并带上缺哪个字段。已清掉这次触发出的两条孤儿单。

判据 ⑩ 纪要一环跑通:决议 → 登记触发 → 工作流 → A1 落到 BD 冯兵,
登记人即来源已记在单上;同一决议重复登记被 412 挡下。

gates: tsc / eslint / depcruise(316 模块)/ api-report / 380 测试 全绿
