Add proxy support for API clients (Binance blocked in some regions)

[xzsean666]

Hey guys 👋

In my region, Binance API is blocked, so NexusTraderd can’t fetch any data or trade properly. It would be super helpful if we could pass a proxy option when starting the service.

Ideally, the proxy setting could be used in:

nexustrader/base/api_client.py (where the requests session is initialized)

All exchange adapters under nexustrader/exchange/ (since they also make HTTP requests)

Hi, @xzsean666
proxy would not be supported, since our websocket dependency picows does not support proxy. You can use vps which provides stable connection in trading and also solve your request issue.
