Features: 1) Add personal_orders_only field to GraphQL schema for Product; 2) Implement personal_orders_only property in Product model; 3) Include personal_orders_only in simple serializer;

Fixes: None;

Extra: 1) Remove redundant `stocks__isnull=False` filter from views and schema queries; 2) Minor formatting adjustments;
