The Proton Drive backend constructed the upstream Proton-API-Bridge
without ever passing rclone's HTTP transport. As a result none of
rclone's HTTP flags reached Proton: --dump headers, --dump bodies,
--no-check-certificate, --user-agent, --bind, --ca-cert, --header,
--tpslimit etc. all silently did nothing for this remote, and HTTP
traffic was invisible to -vv.
Pass fshttp.NewTransport(ctx) through the new Config.Transport hook on
the bridge, which forwards it to the updated go-proton-api's
WithTransport option and so to the underlying resty client.
