refactor: change webhook reception for all instances

This commit refactors the webhook reception to handle all instances at once. Previously, each instance had its own webhook endpoint, but now there is a single endpoint for all instances. This change simplifies the codebase and reduces the potential for errors.

The main changes include:
- Modifying the `InstanceController` to update the webhook URL for all instances.
- Modifying the `WebhookController` to handle the reception of webhooks for all instances.
- Modifying the `IndexRouter` and `WebhookRouter` to add a new route for the webhook reception endpoint.
- Modifying the `ServerModule` to inject the `PrismaRepository` into the `WebhookService`.
- Modifying the `WebhookService` to handle the reception of webhooks for all instances.

These changes improve the maintainability and scalability of the application, as there is no longer a need to manage individual webhook endpoints for each instance.
