Description

Related forum thread: https://forum.pfsense.org/index.php?topic=121105.0

Basically
- disable the enable DHCP server checkbox when there's a /31 or /32 "subnet" configured on an interface
- do not allow saving /31 or /32 on an interface until the user has disabled the DHCP server there (or automatically disable it on save)

It now doesn't enable dhcp on a /31 or /32 subnet, IMO the message "The DHCP Server can only be enabled on interfaces configured with a static IPv4 address. This system has none." could be worded a bit better as there is IPv4 enabled on the subnets, there is just not enough address space to assign DHCP addresses.

Yup looks much better looking at the error message in the source code.
