Add serverip= config option to pin the domain to a LAN IP

The "unsupported protocol" failure was never about HTTPS: the Vita
resolved the public domain to the WAN IP, the router (no NAT loopback)
answered with its own admin page, and curl reported the resulting
HTTP/0.9 garbage as CURLE_UNSUPPORTED_PROTOCOL. serverip= pins the
hostname to the LAN IP via CURLOPT_RESOLVE, keeping Host/SNI intact
for the reverse proxy.
