feat(healthkit): list the accepted sample types on the integration read

GET /api/integrations/healthkit carries acceptedTypes, the quantity and
category identifiers the batch route maps today. The list is derived from
APPLE_HEALTH_TYPE_MAP alone, so a deferred type is never in it and the
client no longer needs a release to follow a mapping change.
