LogicFlow可视化不支持聚合、并行网关

使用LogicFlow画流程图，但是不支持新增的聚合、并行网关，用起来很不方便，手动改数据表的NodeType 后，也无法从logicFlow发布流程。

Start by tracing how LogicFlow node types are handled and how publishing validates or converts them; the issue does not name files or tests. Compare the existing gateway handling with the aggregation and parallel gateway types described in the report. Done means these gateways can be added in the visualization and a process using them can be published without manually editing the NodeType.
