Refactor category filtering in allProducts method of ProductListController

This commit updates the allProducts method to change the way category filtering is handled. It replaces the previous 'category_id' input with 'categories', allowing for a comma-separated string of category IDs to be processed. Additionally, the query now correctly references 'categories.id' for filtering, improving the accuracy of product listings based on selected categories.
