Implement safe category deletion and cascade deletion methods in CategoryController

This commit enhances the CategoryController by adding a safe deletion method that checks for subcategories and associated products before deleting a category. It also introduces a force deletion method that recursively deletes a category and its subcategories. Both methods return appropriate JSON responses for success and error handling, improving the overall category management functionality.
