feat(seo): emit openingHoursSpecification per work location

The doctor page listed where a doctor works but never when, so search engines
had no working hours for any location. booking_locations now carries
opening_hours per context, so each MedicalClinic in the Physician JSON-LD gets
its own openingHoursSpecification, matched to the address by uuid.

Verified against the rendered page: the clinic location emits five shifts with
schema.org weekday URLs alongside the availableService entries.
