The booking-locations endpoint described where a doctor can be booked but not
when, so the public site had no way to emit openingHoursSpecification and had
to fall back to availableService alone.
Each location now carries opening_hours: its active weekly shifts flattened,
with the English weekday name so the consumer can map it onto schema.org
directly. A day with two shifts appears twice; days with no active shift are
omitted. Hours are per context, so the personal practice and each clinic report
their own.
