feature: Webhook

[marconneves]

This new webhook system allows you to receive notifications about events that happen in your account. You can use webhooks to integrate with third-party services, such as a CRM, a marketing automation platform, or a custom
application.

How to create a webhook

1. Go to the Developer settings page and click on the Webhooks tab.
2. Click on the Add Webhook button.
3. Enter the URL of the endpoint that will receive the webhook notifications.
4. Select the events that you want to be notified about.
5. Click on the Create button.

How it works

When an event occurs in your account, such as when an email is sent or a domain is verified, we will send a POST request to the URL that you specified. The body of the request will be a JSON object with the following format:

    {
      "event": "EVENT_NAME",
      "payload": {
        ...
      }
    }

The event property will be the name of the event that occurred, and the payload property will be an object containing the data related to the event.

Caching

To improve performance and reduce the number of database queries, we cache the webhook configurations for 10 minutes. This means that when an event occurs, we will first check if we have the webhook configurations in the cache. If
we do, we will use the cached data to send the webhook notifications. If we don't, we will fetch the data from the database and store it in the cache for future use.

Bug: Function Returns Incorrect Type

The toWebhookEvent function returns string literals (e.g., "EMAIL_SENT") instead of WebhookEvent enum values. This leads to a type mismatch when passed to WebhookService.triggerWebhook, which expects a WebhookEvent type. The function should return WebhookEvent enum values.
