vcontainer: update CLI for bridge networking

Update the CLI wrapper to work with Docker bridge networking:

- qmp_add_hostfwd(): Change QEMU port forward from host_port->guest_port
  to host_port->host_port. With bridge networking, Docker's iptables
  handles the final hop (VM:host_port -> container:guest_port).

- Default network mode: Remove --network=host default. Docker's bridge
  is now the default, giving each container its own IP. Users can still
  explicitly use --network=host for legacy behavior.

- Update help text to document the new bridge networking behavior.

Port forwarding flow is now:
  Host:8080 -> QEMU -> VM:8080 -> Docker iptables -> Container:80
