Fix Instagram authenticated API cookie loading and status reporting

- Handle both cookie formats: flat array and {"cookies": [...]} object
  (scrapers page saves the latter, code only accepted the former)
- Update scraper status to 'ok' after successful authenticated API call
  (previously only set to 'failed' on 401, never cleared on success)
