Status-change history for a licence

GET
/v1/licenses/{license_id}/history

Time-ordered status changes for one licence — active → suspended → revoked, etc. Most recent first. Each row cites the scraper run that detected the change and the regulator URL at the time. Aggregate _meta.freshness_range surfaces the oldest + newest change in the returned window so agents can answer “was there activity in the last 90 days?” in one request.
