Features:

Fixes: 1) Replace `Count("id")` with `Count("pk")` in commerce queries; 2) Fix `User.objects.get(...)` call by using `uuid` directly instead of accessing nested `serializer.validated_data["user"]["uuid"]`; 3) Add missing closing parenthesis in `VerifyJSONWebToken` call.

Extra: Minor code cleanup and consistency in UUID access pattern across mutations.
