- Move notification helper initialization from class-level to lifecycle methods (created/mounted)
- Affected components: ImageMethodDialog, SeedBackupView, QuickActionBvcBeginView, HelpNotificationsView
- Ensures $notify is available when createNotifyHelpers() is called
- Resolves notification errors in image upload functionality
