Add Pothos-generated User GraphQL schema and resolver

This commit adds the Pothos-generated User GraphQL schema and resolver. The schema is defined in the `src/graphql/graphql.schema.ts` file, and the resolver is defined in the `src/graphql/graphql.resolver.ts` file. The schema includes the `User` object type with fields for `id`, `name`, and `email`. The resolver includes a query field `users` that resolves to fetch all users from the Prisma database.
