Fixes #38217 ## Problem Turnstile CAPTCHA verification uses `http.DefaultClient`, so the request to `challenges.cloudflare.com` bypasses Gitea's configured HTTP proxy — unlike other outbound HTTP clients such as the update checker (`modules/updatechecker/update_checker.go`) and migrations. In deployments where egress is only permitted through the configured proxy, verification fails. ## Fix Build the client with `proxy.Proxy()` as the transport proxy, mirroring the update checker: ```go func httpClient() *http.Client { return &http.Client{ Transport: &http.Transport{ Proxy: proxy.Proxy(), }, } } ``` The client is built per call (rather than a package-level var) because `proxy.Proxy()` reads `setting.Proxy` when invoked; building it at request time ensures it reflects the loaded settings. When no proxy is configured, behavior is unchanged (`proxy.Proxy()` returns a no-op / `http.ProxyFromEnvironment`). --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
