Missing service alias for WebPush\WebPushService interface

[Spomky]

Problem

The bundle registers WebPush\WebPush as a service in the container (in Resources/config/services.php), but does not create an alias for the WebPush\WebPushService interface it implements.

This means users who properly type-hint the interface (following dependency inversion principle) get an autowiring error:

Cannot autowire service "...SendPushNotificationHandler": argument "$webPush" of method "__construct()" 
references interface "WebPush\WebPushService" but no such service exists. 
You should maybe alias this interface to one of these existing services: "WebPush\WebPush", "web_push.service".

Expected Behavior

The bundle should register an alias from WebPush\WebPushService to WebPush\WebPush so that autowiring works with the interface.

Current Workaround

Adding a manual alias in services.yaml:

WebPush\WebPushService: '@WebPush\WebPush'

Suggested Fix

In web-push-bundle/Resources/config/services.php, add:

$container->alias(WebPushService::class, WebPush::class);
