feat(test-app): default notification time to current + 3 minutes

Replace hardcoded '09:00' default with dynamic calculation that sets
the notification time to 3 minutes from now (rounded up to next minute).
This makes it more convenient for users to quickly test notifications
without manually adjusting the time field.
