Workout Consistency heatmap tooltip hidden behind frame on top rows

Bug Description

When hovering over any box in the top three rows of the Workout Consistency heatmap (on the Trends/Overview tab), the tooltip is hidden behind the frame/container and not visible to the user.

Steps to Reproduce

1. Go to Analytics > Overview tab (or Trends > Overview)
2. Scroll to the Workout Consistency heatmap
3. Hover over any cell in the top 3 rows
4. Tooltip is cut off or completely hidden

Expected Behavior

Tooltip should be fully visible, either by:

• Rendering above the container with higher z-index
• Flipping tooltip position when near top edge
• Using a portal to render outside the container

Technical Notes

• Component: WorkoutHeatmap.tsx
• Likely needs tooltip overflow handling or position adjustment for top rows
