A patch: omitted fields are left alone.

Renaming retags every product that carried the old label, because the label is the join key rather than an ID.

**Errors**

- `404 category_not_found` — unknown ID, or one belonging to another tenant.
- `409 category_name_taken` — the new label already exists.
- `409 preset_category_immutable` — a built-in category can't be edited.
