feat: add async prerequisite installation with retry logic and visual feedback

This commit enhances the boarding flow to handle prerequisite installation asynchronously with proper retry logic and user feedback:

- Add retry mechanism with max 3 attempts for prerequisite installation
- Display live installation logs via ActivityMonitor during boarding
- Reset ActivityMonitor state when starting new activity to prevent stale event dispatching
- Support dynamic header updates in ActivityMonitor
- Add prerequisitesInstalled event handler to revalidate after installation completes
- Extract validation logic into continueValidation() method for cleaner flow
- Add unit tests for prerequisite installation logic

This improves UX by showing users real-time progress during prerequisite installation and handles installation failures gracefully with automatic retries.
