feat: 流程编辑器 bpmn-js 画布模式 + 引擎多出口/退回/移交/或签前端接线

- def-editor 新增画布模式（默认）：bpmn-js 内存画布（精简 palette/汉化/撤销重做/缩放/出口命名/导出 BPMN）， toBpmn/fromBpmn 双向序列化，contentJson 仍为持久格式（+layout 坐标）；卡片模式保留回退 - 新增 utils/flowLayout.ts 分层布局（设计器与查看器共用） - TaskHandle：多出口节点出口选择下拉；退回/移交按钮与弹窗；轨迹显示已退回/已移交及所选出口 - FlowDiagram：优先使用保存坐标；边画出口名标签；办件状态着色/当前节点高亮 - api/flow：approve 带 edgeName，新增 returnBack/transfer
