Improved ipv6 friendlyness

Is your feature request related to a problem? Please describe

In voron #klipper, we're seeing more and more frequent issues with people having ipv6 working in their networks, and mapped by their host names, but not in the moonraker trusted hosts.

Describe the solution you'd like

I would propose a disabled by default feature, where moonraker autodetects the ipv6 subnet it is in, and automatically adds it to trusted_hosts.

This way, moonraker would still be secure by default, but users would also have a friendly way to solve ipv6 based connection failures.
