Anything that belongs to a service is defined on the service itself, so the
two tabs that managed selection groups and appointment segments come off the
service page.
Only the UI goes. SegmentTemplate is what makes a service occupy a room and a
device at the same time — it is the input to AppointmentPlanBuilder and the
reason the resource timeline has anything to draw — and a service without a
template already books through singleSegment(). Removing the model would
change booking; removing the tabs does not, which tests/Appointment confirms
at 314 green.
The active tab moved into the query string on the way past. That is what
makes the old ?tab=segments link land on the info tab instead of rendering
nothing, and it lets back and refresh return to the same tab.
