Fix hostname and TLS config for gateway

- Change hostname from antigravity.dev.farh.net to antigravity.farh.net
  to match the gateway's *.farh.net listener
- Set SECURE_CONNECTION=0 since TLS is terminated at the gateway,
  avoiding the redirect loop caused by the app doing its own HTTP->HTTPS redirect
