feat(client): create test mock factories for GraphQL types

[wreality]

Summary

Test files pass partial mock objects for generated GraphQL types (e.g. User, Submission, Publication). These types have many required fields that tests don't care about, leading to either as any casts or type errors.

Proposed solution

Create factory helpers in test/vitest/ that produce properly typed mock objects with sensible defaults, overridable per-test:

// test/vitest/factories.ts
import type { User } from "src/graphql/generated/graphql"

export function mockUser(overrides: Partial<User> = {}): User {
  return {
    __typename: "User",
    id: "1",
    email: "test@example.com",
    username: "testuser",
    name: "Test User",
    ...overrides
  }
}

Files needing factory usage

• src/components/AssignedSubmissionUsers.vitest.spec.ts — partial User in reviewers arrays
• src/components/AssignedPublicationUsers.vitest.spec.ts — partial User in editors arrays
• src/components/forms/AccountProfileForm.vitest.spec.ts — accountProfile: {} as any
• src/use/forms/graphQLValidation.vitest.spec.ts — error.value = {} as any
• src/components/PublicationStyleCriteria.vitest.spec.ts — (form().at(0) as any).vm.$emit(...)
• src/components/forms/StyleCriteriaForm.vitest.spec.ts — (wrapper.emitted("delete")![0][0] as any).id
