feat: Enhance Step 9 diagnostics and error handling

- Refactor getStatusBadgeEntries to use createStep9Entry for better encapsulation.
- Introduce error visual signals detection in createStep9Entry.
- Add functions to identify OAuth callback timeout failures and step 9 failure texts.
- Update buildStep9StatusDiagnostics to include error visual summaries and handle conflicts between success and failure states.
- Implement new tests for step 9 diagnostics, ensuring correct behavior with success badges and error banners.
- Remove outdated tests related to step 5 onboarding and redirect race conditions.
- Add new tests for auto-run behavior in step 6 restart scenarios.
