`move` moves a category to a new parent. Both `id` (source) and `parentId` (target) are validated via `resolveCategoryAccess` — the target must be a real category of the same authorized company, else `Parent not found`. Moving into itself or into a descendant (cycle) → `Invalid parent`. The moved category gets the next sibling `sort` under the new parent. Returns `{ id, parentId, sort }`. For `POST /api/category/:id/move`.
