fix: saveAndWait must also wait for isTemporary to become false

The share dialog's refreshDialogState() checks workflow.isTemporary —
if true, it shows 'unsaved' state. After saving a temporary workflow,
the backend response updates size (making isTemporary false), but the
test was only waiting for isModified === false, creating a race where
the dialog could open before the workflow was fully persisted.
