[To Do]: Add enable DHCP to WiFi setup code

[peteGSX]

Task description

As reported in Discord, if for some reason the DHCP server capability of the ESP01 is disabled, it will not automatically enable again when in AP mode, and the AT command must be manually executed: AT+CWDHCP_DEF=0,1

Resolution posted by @Asbelos is to add this command to the WiFi setup code to ensure it is always enabled in AP mode.
