Features: 1) Add image_url property to Category and ProductImage models for constructing absolute image URLs; 2) Replace direct image.url references with image_url across serializers and GraphQL resolvers;

Fixes: None;

Extra: 1) Simplify serializer methods by removing redundant `suppress` blocks for `image.url`; 2) Minor adjustments to GraphQL resolver parameter names for consistency.
