[Feature Request] Update guide/docs to include details on which subnet/LAN the VMs can be found from the host machine

[gabefair]

Hello it is not clear to newbies (like me) where I can find the VM's assigned ip address.
https://docs.getutm.app/settings-qemu/devices/network/network/

Its not available on the details or status window:

After the machine starts and receives its lease from whatever gateway its using, it would be really helpful if the IP address appeared on the status window. Docker does this.

The online documentation and setup guide could be updated to help others answer questions like:
What is the default LAN that is used by UTM?
What happens if I'm running more than 255 machines? Whats the CIDR block UTM defaults to?
What error would I get if that default LAN is already fully occupied?

I would submit a PR, but I don't yet have the answers to these questions.
