 * Tell Acta this site is disconnecting, before the credentials are deleted.

 * Acta marks the publisher inactive so it stops serving the paywall and stops
 * taking payments it can no longer fulfil — once this plugin is gone, article
 * content can no longer be fetched from the site.
 *
 * Nothing is deleted on Acta's side. The account, Stripe details and any
 * balance owed are kept, so reinstalling reconnects to the same publisher.
 *
 * Best-effort: uninstall must never be blocked by a network problem, so
 * failures are ignored. Acta also detects removal on its own.
 *
 * This file runs standalone — the main plugin file is not loaded, so the
 * backend URL cannot come from ACTA_BACKEND_URL and is repeated here.
