feat: JSON编辑器增强 - Token映射下拉、字段选项key:value、序列化始终包装type

1. 模型配置弹窗: Token映射三个字段由输入框改为下拉菜单
   - 同步/流式从响应映射取key, 异步从回调响应映射取key
   - 切换返回类型时清空Token映射, 无映射配置时禁用并提示
2. JSON编辑器序列化: 所有节点始终输出{type, value/attrs}格式
   - 容器(object/array)始终{type, attrs}, 标量始终{type, value}
3. 字段配置增强:
   - 对象类型新增"循环生成"开关
   - 下拉控件选项列表改为key:value双输入框
4. 类型注释更新
