Features: 1) Add ProductTagType to GraphQL schema with associated queries and resolvers; 2) Register ProductTagViewSet in API URLs and core router; 3) Implement detailed and simple serializers for ProductTag.

Fixes: 1) Correct `serializer_class` assignments for `ProductImageViewSet`, `PromoCodeViewSet`, `PromotionViewSet`, `StockViewSet`, and `WishlistViewSet`.

Extra: 1) General code cleanup and reorganization for viewsets.
