[4.x]: Gateway Events

[AugustMiller]

What happened?

Description

Events are not currently emitted by craft\commerce\base\Gateway or craft\commerce\services\Gateways when saving a Gateway’s configuration.

Craft typically emits events from the service class when saving Project Config-bound changes (beforeSave when modifying values, then afterSave in a PC event handler). The model events appear to be less consistently triggered…

Steps to reproduce

1. Add a listener in a custom module:

   use craft\events\ModelEvent;
   use craft\commerce\base\Gateway;
   use yii\base\Event;
   
   Event::on(
      Gateway::class,
      Gateway::EVENT_BEFORE_SAVE,
       function(craft\events\ModelEvent $event) {
           Craft::dd('Got it!');
       }
   );
   

2. Save a new or existing gateway

Expected behavior

• Using the example code, the page is halted.
• I should also be able to listen to events from the service class, i.e. craft\commerce\services\Gateways::EVENT_BEFORE_SAVE_GATEWAY.

Actual behavior

No event is triggered.
