fix(credential-groups): await the refetch before clearing the edit buffer

The update mutation fired its invalidations without returning them, so
mutateAsync resolved before the refetch landed. Callers that clear their
draft on success then fell back onto the pre-save cache and flashed the old
name and description until the refetch completed — or kept showing them if
it failed.
