fix(ci): separate reload request from test request to handle 302 redirect

Wheels returns HTTP 302 after reload=true completes. The test curl was
capturing this 302 as a failure instead of following the redirect.

Fix: issue the reload as a separate curl with -L (follow redirects),
then run the actual test request without reload.
