Update Categories
Rename and/or reparent categories by id. Each item sets name (rename), parent_id (move; null = promote to top level), or both — at least one is required. A combined edit is applied move-then-rename. Returns per-item results — the batch never fails as a whole. Rejection reasons: not_found, name_conflict, invalid_move (would nest a category inside itself).
