fix(emqx): increase disk to 6GB and add optional MQ disable prompt

EMQX 6.1+ preallocates significant disk space for the MQ feature,
causing high CPU/disk usage on small containers (emqx/emqx#16649).

- Increase default disk from 4GB to 6GB
- Add read -rp prompt during install to optionally disable MQ feature
  via mq.enable=false in emqx.conf (reduces disk/CPU overhead)
- Setting is in install script (not CT script) per reviewer feedback
