/**
 * Normalizes the `filters` response to the nested count object the smartfilter components
 * consume. This is the sole source for smartfilter option counts.
 *
 * Counts are filter-aware only when the query was sent with an asset filter; without one the
 * gateway returns portal-wide counts. Options with no assets under the active filter are
 * already dropped server-side, so anything arriving here is expected to have a count.
 *
 * Keyed by id rather than label because labels are localised.
 *
 * Output format:
 * {
 *   smartfilterId: {
 *     metapropertyId: {
 *       optionId: count
 *     }
 *   }
 * }
 *
 * @param filterData - GraphQL `filters` response
 * @returns Normalized nested counts by id
