 * Registers the order-edit "Send abandoned cart recovery email" action and routes

 *
 * This lives outside the email class because the email is only instantiated
 * when `WC_Emails::instance()` is first called, which doesn't reliably happen
 * before `WC_Meta_Box_Order_Actions::save()` dispatches the order-action hook.
 * Registering the hooks from this container-managed service guarantees the
 * listener is in place at admin POST time. The callbacks lazy-load the email
 * instance via the mailer so the heavy email class only gets loaded when it's
 * actually needed.
 *
 * The container auto-calls `init()` after instantiation; resolution is driven
 * by `WooCommerce::maybe_init_abandoned_cart_recovery()`, hooked on `init` priority 1.
 *
 * @internal Just for internal use.
