Change to send external workflow deletion notification after the workflow deletion is completed.

[Copilot]

Pull request overview

This PR fixes a bug where external workflow deletion notifications were sent before the workflow deletion was completed. The change ensures the notification is sent only after the deletion process finishes successfully.

Key changes:

• Reordered deletion logic to call deleteWorkflowData before creating the notification event
• Removed isDeletionInitialized method and all references as it's no longer needed for the new flow
• Updated tests to mock deleteWorkflowData instead of isDeletionInitialized
