refactor: standardize notification usage in ChoiceButtonDialog.vue

Add notify helper property and initialize in created() with createNotifyHelpers(this.$notify)
Replace direct $notify call in open() with this.notify.confirm(...) and use TIMEOUTS.MODAL for duration
Remove unused NotificationIface import
Add $notify property for Vue runtime injection to satisfy type checker
Ensure all notification usage is consistent with project best practices
This ensures maintainable, type-safe, and consistent notification handling in the ChoiceButtonDialog component.
