fix(forwarder): record post-rewrite URI in HTTP recorder

After RewriteURL mutates req.URL.Path, ro.HTTP.URI still held the
pre-rewrite value because the recorder object was initialized before
the rewrite loop. Update ro.HTTP.URI to match the rewritten path so
the recorded HTTP request reflects the URI actually sent upstream.
