Purpose

This PR addresses DYN-8072 where users were not always prompted to save changes when opening a new graph from the Recent Files section.

Changes Implemented:

• Ensured that AskUserToSaveWorkspaceOrCancel is called when opening a new graph.
• Updated HasUnsavedChanges handling.
  Now, after the user confirms saving or discarding changes, workspace.HasUnsavedChanges is properly set.

Expected Behavior After the Fix:

• If the current graph has unsaved changes, the user will always be prompted before opening a new graph.
• If the user chooses to save or discard changes, HasUnsavedChanges is correctly updated.
