 * admin panel without a restart — consistent with the plugin's panel-managed
 * model. `server-only` keeps the SMTP password out of any client bundle.
 *
 * Returns a result object rather than throwing, so callers (e.g. form
 * submission) can handle failure without a try/catch and never leak SMTP
 * details to the client.
