Check profiles

Review a described business profile before generating it, as the signed-in member: every attached upload must be ready, and the description and the files' names are screened for acceptable use (a denial is POLICY_DENIED with the reason to show). Then one included (unbilled) web search matches the description: match.reading is what the words themselves say about the subject (name, entity type, affiliation, role, location, website; null where unsaid) and match.candidates the public matches it found, best first, none when it found none. Returns the files generate will read and the match. Call business_profiles_generate with the same description, attachmentIds and Idempotency-Key, and subjectMatch {id, candidateIndex} for the candidate the member confirmed (null for none), to reuse this screen.
