refactor: streamline variant and price loading in product-related services

- Removed unnecessary ordering by 'created_at' in variant loading across multiple services and models.
- Implemented global scopes for ordering product variants and raw material prices by 'name' and 'variant', respectively.
- Enhanced code readability and maintainability by simplifying query structures in ProductController, OrderService, and others.
