 * One-off diagnostic: dumps the request_json and response_json for the most
 * recent "consent_request" workflow rows, to see the RAW bridge response
 * behind a generic "HTTP 400" error shown in the New Consent Request modal.
 *
 * Usage:
 *   php83 check_consent_request_400.php          -> last 5 consent_request rows
 *   php83 check_consent_request_400.php <id>     -> full dump for one row id
 *
 * Reads DB credentials from the app's own .env (does not print them).
