feat(notification): ✨ Remove notification when read externally (#707)

* feat(notification): ✨ Add notification removal feature

Implemented a new method `RemoveNotificationAsync` in the `INotificationBuilder` interface to allow the removal of toast notifications for specific emails identified by a unique ID.

This change enhances the notification management by ensuring that notifications can be cleared when emails are marked as read. The `NotificationBuilder` class has been updated to include logic for removing existing notifications and to use the unique ID as a tag for the toast notifications, facilitating their removal. Additionally, the `AppShellViewModel` has been modified to call this new method when an email is updated and marked as read.

This improvement aims to provide a better user experience by keeping the notification area relevant and up-to-date.

* feat(notification): ✨ Add MailReadStatusChanged event handling

Introduced a new event system for handling email read status changes. This includes the addition of a listener in `NotificationBuilder` that removes notifications when an email is marked as read.

• Added `MailReadStatusChanged` record to represent the event.
• Registered a listener in `NotificationBuilder` to handle notification removal.
• Removed the `OnMailUpdated` method from `AppShellViewModel`, delegating notification management to the new event system.
• Updated `MailService` to send `MailReadStatusChanged` events when emails are marked as read.

This change improves the communication between components and enhances the notification management system.

* refactor: Remove comments

* Little cleanup.
