Add service-point routing so call-next cannot steal assigned tickets.

Counters gain destination/staff metadata; tickets can be pre-assigned to a
service point with assigned_only queues for healthcare while shared_pool
preserves generic bank/government behavior. Display and announcements expose
ticket, staff, and destination clearly for Care and public boards.
