Publish noVNC on host:16080 to bypass WS-stripping reverse proxy

The upstream openresty proxy in front of Dokploy strips the
WebSocket Upgrade header, which kills noVNC. Publishing noVNC
directly on a host port (16080) avoids the proxy entirely.
Auth is still gated by VNC_PASSWORD. The dashboard continues
to go through Traefik on its existing domain.
