首页工作流节点引用多选与保存回显完善：isMultiParameter 全链路透传 + valueSource 数组化/label + 旧 DSL 兼容

- isMultiParameter 节点级开关从节点库透传至引用下拉，支持多选勾选/去重/逐条删除/清空
- valueSource 契约统一为数组并补 label（节点名.字段中文名），覆盖用户引用、表单展示标记与旧 DSL 单对象
- ModelField 递归透传 multi，object/array 嵌套子字段同样支持多选
- 保存/回显兼容旧 DSL 单对象 valueSource，重开自动升级为数组
- modelRequestParamsPath 每项新增 label 字段，后端按 path 重组请求参数
