Fix test failures in GitHub Actions workflows

- Add envtest setup before running tests
- Use 'make setup-envtest' to install test binaries
- Use 'make test' instead of direct go test
- Ensures proper test environment setup in CI

This fixes the BeforeSuite panic caused by missing envtest binaries.
