Purpose

This PR addresses DYN-7719, where the New and Open shortcut buttons blink during graph execution in Periodic Run mode.

The flickering was caused by RunSettingsViewModel.NotifyOfGraphRunChanged, which was toggling the IsEnabled state of UI elements on every execution cycle. To resolve this, UI updates are suppressed when DynamoModel is in Periodic Run mode, preventing unnecessary changes to the shortcut buttons.
