Returns the most recent stored insight report for a target identity (store + review site + period + theme), read entirely from our database — it never calls ReviewData and never consumes usage. When no matching report exists, data.found is false, signalling the UI to offer a Generate action.

Auth: Both — authentication; store_id scoped by an ownership check (auth-company-tree walk). A Partner reaches any store in its sub-tree; an Account only its own stores. The match also keys on review_site_id (null vs specific), year, month (null = full-year), and theme, returning the latest (id) match.

Rate limit: No rate limit.
