Update a facility location (simple CoreLocation fields)

Updates allowed CoreLocation fields for a location linked to the facility. Requires consentAcknowledged: true. Includes contacts, office hours, ADA, limitations, isPrimaryLocation (primary indicator), optional userDefinedFields (full replace of that object on CoreLocation data), and optional specialityDetails (same shape as add-location; syncs TenantFacilityLocationSpecialty via replace semantics). Location name and service address cannot be changed via this API (crosswalk safety). The authenticated user is the actor (updated_by); scoped effective-date PATCH and cascade to group/network denormalized rows are not part of this endpoint.
