 * wp_* columns and retires the per-site secret), then clears the plugin's
 * stored options. The signed request is built inline because the plugin's
 * classes are not loaded during uninstall.
 *
 * Order meta written by the plugin (_adverships_*) is intentionally left in
 * place so historical orders keep their attribution; it can be removed via the
 * privacy eraser.
