Lovepreet Singh 65c5a5ff7b fix(turnstile): route CAPTCHA verification through the configured proxy (#38412)
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`).
