ui: configure tethering based on prime type (#23733)

* Store prime type in param

* set tethering metric based on prime type

* update existing connections

* returning zero is fine

* always set

* add callback on activate

* call systemctl

* match server enum

* add delay

* assume field is there

* snake case
