google-labs-jules[bot] 80cfe71e59 refactor: Refactor GraphQL tests to use mock-based unit tests
This commit refactors the GraphQL test suite to resolve persistent build failures and establish a stable, mock-based unit testing environment.

The key changes include:
- Consolidating all GraphQL test helper functions into a single, canonical file (`internal/adapters/graphql/graphql_test_utils_test.go`).
- Removing duplicated test helper code from `integration_test.go` and other test files.
- Creating a new, dedicated unit test file for the `like` and `unlike` mutations (`internal/adapters/graphql/like_resolvers_unit_test.go`) using a mock-based approach.
- Introducing mock services (`MockLikeService`, `MockAnalyticsService`) and updating mock repositories (`MockLikeRepository`, `MockWorkRepository`) in the `internal/testutil` package to support `testify/mock`.
- Adding a `ContextWithUserID` helper function to `internal/platform/auth/middleware.go` to facilitate testing of authenticated resolvers.

These changes resolve the `redeclared in this block` and package collision errors, resulting in a clean and passing test suite. This provides a solid foundation for future Test-Driven Development.
