wger: Use $http_host for proxy Host header

Update the nginx config to set the proxied Host header from $http_host instead of $host. This preserves the original Host header sent by the client (including port) when forwarding requests, avoiding mismatches that can occur when $host omits the port or falls back to server_name.
