Add common4j-local unit tests for new onboarding fields

The Common Code Coverage Compare PR-vs-Dev pipeline only counts coverage
contributed by tests in the same module as the production code. Our existing
adapter round-trip tests live in common (Robolectric) and exercise the
common4j fields indirectly through Gson/Lombok-generated getters/setters,
but those calls don't show up in the common4j JaCoCo report.

Adds two small common4j-local unit test classes that directly exercise the
new fields, restoring full coverage on the changed lines:
- AcquireTokenResultTest: getOnboardingBlob/setOnboardingBlob with default,
  set, and clear cases.
- InteractiveTokenCommandParametersTest: getOnboardingSeedJson default and
  round-trip through the Lombok builder.
