 * Groups normalised fact sheets into named clusters based on up to 2 clustering dimensions.

 * @param data - Normalised fact sheets (`AttributeMap[]` from `mapFactSheetsToAttributeMaps`)
 * @param config - Configuration with `clustering` (1–2 `ClusterConfig` items) and optional `view`
 * @returns A sorted array of `Cluster` objects, each containing an `id`, `label`, `color`, and `items`
 * @throws Error if `config.clustering` contains more than 2 entries
