/**
 * Render an optional exact-total control for an authorized administrator workflow.
 *
 * The control deliberately renders only when the Business Small cost engine is
 * available. It does not submit itself because both supported inspectors live
 * outside the native Booking Form. Their page adapters copy a non-empty value
 * into the dedicated booking-create request parameter, which is authorized and
 * validated again by the shared server save boundary.
 *
 * @param array $args {
 *     Control presentation arguments supplied by trusted plugin code.
 *
 *     @type string $input_id      Unique HTML input ID.
 *     @type int    $resource_id   Optional Booking resource used for its currency symbol.
 *     @type string $wrapper_class Wrapper CSS classes.
 *     @type string $label_class   Label CSS classes.
 *     @type string $control_class Control-container CSS classes.
 *     @type string $input_class   Number-input CSS classes.
 *     @type string $help_class    Help-paragraph CSS classes.
 *     @type string $label         Translated field label.
 *     @type string $placeholder   Translated empty-value placeholder.
 *     @type string $suffix        Translated suffix displayed after the number.
