feat(dashboard): add Recent Events widget for v2 system

- Add registerRecentEventsWidget() in infoBoxWidgets.js
- Implement notebook-style UI with rings, bullet points, and editable events
- Support max 3 events with + placeholders for new entries
- Parse 'Recent Events: event1, event2, event3' format from infoBox
- Register widget in dashboardIntegration.js
- Add to default layout Scene tab (row 4-5, below location)
- Integrate with tracker system:
  - Add to WIDGET_TO_TAB_MAP (maps to tab-scene)
  - Add to shouldWidgetBeRemoved() rules
  - Add to detectConfigChanges() for re-addition support
- Completes v2 widget migration - all tracker features now have widgets
