/**
 * Delivers the initial admin credentials once provisioning completes.
 *
 * Sent SYNCHRONOUSLY from CompleteProvisioning (not queued): the step only
 * records the `credentials_sent` breadcrumb and scrubs the password AFTER the
 * send returns, so a mail failure re-runs the step (password preserved) instead
 * of losing the credential in a failed queue job. Delivery is at-least-once — a
 * crash in the tiny window after send but before the breadcrumb can re-send a
 * duplicate welcome email, which is preferable to a lost credential.
