All Fanvil V6x phones share the same <sysConf> XML provisioning schema
and {$mac}.cfg filename convention, so each of the new templates is a
copy of the existing v67 template with <UseVendorClassID> set to 0 and
<VendorClassID> set to a generic "Fanvil" string. This avoids coupling
the templates to a single model's DHCP Option 60 identifier while
letting operators pick the matching device type in the provisioning UI.
