fix: initialize notification helpers in lifecycle methods

- Fix 't is not a function' error during image upload by properly initializing notification helpers
- 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
