Function newTestServer

cmd/cache-proxy/proxy_test.go:101–107

newTestServer returns an httptest origin plus a proxy that rewrites inbound forward-proxy-style requests to target that origin. DuckDB sends absolute-form URIs (scheme + host + path); we give the test the origin's URL so the proxy's fetchOrigin hits httptest.Server directly.
