HRV balanced dots, dashed gap lines, dashboard widgets + drag-to-edit layout
- Green dots for balanced HRV (joining orange unbalanced / red low) on the trend
- Trend charts bridge data gaps with a dashed line instead of a blank break
- Dashboard: drop Health today; add VO2 max, small sleep, and HRV status widgets
- Dashboard: editable widget grid (react-grid-layout) with drag/resize, saved per-user
