Proxy is not respected

从 GraphClientFactory.create_with_default_middleware 和 GraphRequestAdapter 开始，然后比较直接的 AsyncClient 请求与 GraphServiceClient 请求。使用提供的代理配置重现超时，并跟踪已配置的 AsyncClient 是否在 middleware 和 adapter 中得以保留。完成标准是 Graph 请求使用已配置的代理，而不是发生超时。

I followed the steps here and its not using the proxy at all. My requests just time out: https://learn.microsoft.com/en-us/graph/sdks/customize-client?tabs=python#configuring-the-http-proxy-for-the-client

While normal requests using httx work, the requests to Azure do not. I'm guessing that this new client is not accepted somewhere down the chain
