/**
* Creates a GroupByArgsFrom mixin with REST API decorators.
* This function extends the base GroupByArgsFrom functionality to include
* proper Swagger decorators for REST APIs.
*
* @template T - The entity type (optional, for type inference)
* @param config - Configuration with FindArgs type, fields, and optional class options
* @returns A dynamically generated GroupBy class with REST API decorators
*
* @example
* ```typescript
* import { GroupByArgsFrom } from '@solid-nestjs/rest-api';
*
* export class FindProductArgs extends FindArgsFrom({
* whereType: ProductWhere,
* orderByType: ProductOrderBy
* }) {}
*
* // Using field names
* const ProductGroupByFromArgs = GroupByArgsFrom({
* findArgsType: FindProductArgs,
* groupByFields: ['category', 'supplier', 'status'],
* className: 'ProductGroupByFromFindArgs',
* options: {
* description: 'Group by fields for Product queries'
* }
* });
*
* // Using generated fields class
* const ProductGroupByFields = createGroupByFields(Product, {...});
* const ProductGroupByFromArgs = GroupByArgsFrom({
* findArgsType: FindProductArgs,
* groupByFieldsType: ProductGroupByFields,
* options: {
* description: 'Group by fields for Product queries'
