Add settings option to replace 'ports' with a Traefik label template + custom docker network.

Love the idea of this app!
This may be a bit out of scope for this app as it seems geared towards people just starting out with homelabs, but I still think there is a place for allowing a bit more customization and room to grow.
Ending up using a reverse proxy and custom domains seems like a logical next step for someone who has gotten the hang of running docker-compose files.

Currently, the only thing that is stopping me from directly copy pasting these files without any modifications is that I mostly use traefik labels instead of port mappings.
I understand there are many different reverse proxies and configurations that people use so don't expect a one size fits all approach, but would love a section in the settings to add my own default label template and toggle on/off the default port mappings.

about 90% of the containers I run have a template such as this:

      - com.centurylinklabs.watchtower.enable=true
      - traefik.enable=true
      - traefik.docker.network={PROXY_NETWORK}
      - traefik.http.routers.${APP_NAME}-http.rule=Host(`${APP_NAME}.${DOMAIN}`)
      - traefik.http.routers.${APP_NAME}-http.entrypoints=http
      - traefik.http.routers.${APP_NAME}-http.middlewares=https-redirectscheme@file
      - traefik.http.routers.${APP_NAME}.rule=Host(`${APP_NAME}.${DOMAIN}`)
      - traefik.http.routers.${APP_NAME}.entrypoints=https
      - traefik.http.routers.${APP_NAME}.middlewares=${MIDDLEWARE_CHAIN}
      - traefik.http.routers.${APP_NAME}.tls=true
      - traefik.http.services.${APP_NAME}.loadbalancer.server.port=${APP_PORT}
      - traefik.http.services.${APP_NAME}.loadbalancer.passhostheader=true

This might be overkill, and could probably be made more generic, but I think there is power in allowing further customization of the defaults.
