feat: Adds IPv6 disabling feature (#803)

* Allow disabling IPv6

Simply ignores any IPv6 addresses in the lease and doesn't offer them to the RPC
Also fixed display issue for IPv6 link local address.
Fixes https://github.com/orgs/jetkvm/projects/7/views/1?pane=issue&itemId=122761546&issue=jetkvm%7Ckvm%7C685

* Don't listen on disabled addresses in mDNS or web server.

* We have to set the IPv4 and IPv6 modes on the server.
