📔 Objective

This pull request introduces support for handling premium status change notifications across the application. The main changes add a new PremiumStatusChanged notification type, update the notification processing logic to handle this new type, and ensure that the premium status is correctly updated in the user's billing profile state.

Notification Type and Model Additions:

• Added a new NotificationType.PremiumStatusChanged enum value and corresponding PremiumStatusChangedNotification model to represent premium status change events. [1] [2]
• Updated the NotificationResponse class to handle deserialization of the new notification payload.

Notification Handling Logic:

• Updated DefaultServerNotificationsService to inject and use BillingAccountProfileStateService for processing PremiumStatusChanged notifications, updating the user's premium status accordingly.

🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR adds a new PremiumStatusChanged push notification type so client apps can react to premium status changes without waiting for a full sync. The implementation adds the new enum value, a typed payload (PremiumStatusChangedNotification), wires BillingAccountProfileStateService into DefaultServerNotificationsService, and updates DI in both the Angular module and the browser background service. Tests cover the true/false payload paths, preservation of the existing hasPremiumFromAnyOrganization value, and that no full sync is triggered.
