fix(knowledge): derive tags modal document data from live list cache

The modal was fed a frozen document snapshot taken at right-click time. After a save, the mutation only invalidates the single-document and KB-detail queries (not the documents list query), so the modal's own sync effect rebuilt tags from the stale snapshot and could revert or drop the just-saved value. Track only the document id and look it up from the same documents array updateDocument() patches, so the modal always sees current data.
