Refactor integration test targets in Makefile and update workflow

- Renamed integration test targets in the Makefile for clarity: `integration-tests` to `integration-tests-all` and added `integration-tests-basic`.
- Updated GitHub Actions workflow to run the new `integration-tests-basic` target.
- Cleaned up the `WithAuth` test class by removing unused imports and simplifying method signatures.
