Add 3 passing UI tests (batch 5): heatmap, reduce motion, high contrast

- TC-148: Year View heatmap grid renders with data (added accessibility ID)
- TC-143: App navigable with Reduce Motion enabled
- TC-144: App navigable with High Contrast mode enabled
- Marked 89 blocked tests RED in QA spreadsheet
