Refactor product relations to use new category_product and channel_product tables

- Updated queries and relationships in various controllers and models to replace `product_has_relations` with `category_product` and `channel_product`.
- Adjusted methods in `ProductFilterer`, `FilterParamsController`, and `FilterController` to reflect the new database structure.
- Modified seeder to insert data into the new `channel_product` table.
- Updated tests to ensure compatibility with the new product relation structure.
