Wrong host names displayed in "Outbound API Requests" when requests are sent via a proxy.

[cjsoftuk]

How do you use Sentry?

Self-hosted/on-premise

Version

2.47.0

Steps to Reproduce

1. Configured environment variables http_proxy, https_proxy to send requests out via a proxy server (running tinyproxy).
2. Inspected the "Outbound API Requests" feature in the web interface
3. Observed that requests made via the proxy are logged with the proxy's hostname and port, rather than the eventual destination.

Expected Result

I'd expect to see these showing as calls to https://onlinetools.ups.com/api/track/v1/details/

Actual Result

The calls to /api/track/v1/details/ are actually calls to https://onlinetools.ups.com/api/track/v1/details/, but show up as calls to https://bde-proxy.dchosted.net:8888/api/track/v1/details/ in the web UI
