Description
This PR fixes a bug in the JWT middleware that causes the JWK fetch process to not honor HTTP proxy environment variables.
Related Issue
Motivation and Context
In restricted corporate environments, it's common to require all HTTP traffic go through a proxy server. The default transport pulls proxy settings from the standard environment variables, but it looks like this was inadvertently removed to support disabling TLS cert verification when fetching JWK sets. This fix restores the ability to support standard proxy environment variables.
How This Has Been Tested
All JWT middleware unit tests pass. I didn't add unit tests for this functionality because
http.ProxyFromEnvironment
caches the config making tests that rely on env vars very flaky.Screenshots (if appropriate)
