/**
|
|
* 编辑器 / 监控页对 SimpleLite SSE 的事件订阅封装，把以下 5 类事件转给业务回调：
|
|
*
|
|
* - `alarm` (来自 AlarmStreamService)：报警新增/更新/解除
|
|
* - `object-created` (来自 MapEditApiController)：对象创建后
|
|
* - `object-deleted` (来自 MapEditApiController)：对象删除后
|
|
* - `object-patched` (来自 MapEditApiController)：对象字段被 patch 后
|
|
* - `object-batch-changed`(来自 batch / ai 调用)：一组对象变化，建议直接整页重拉
|
|
* - `pick-result` (来自 /pick)：拾取会话完成
|
|
*
|
|
* 业务页只用关心自己感兴趣的事件回调，其它走默认忽略。
