fix(*.cs): Refactor notification unread property and update UI binding

Renamed 'isUnread' to 'IsUnread' in NotificationModel for consistency with C# naming conventions and updated all references in the ViewModel. Modified NotificationView.xaml to use IsEnabled instead of Visibility for the mark-as-read button, removing the BooleanToVisibilityConverter resource.
