Improve analysis dashboard UI

- Fix chart y-axis to use suggestedMax (0.2) instead of max (1.0) for better visibility of low toxicity values
- Improve decimal precision in chart tooltips (0.1% instead of 0%)
- Style quick-link buttons with solid background, shadow, and hover effects like Bluesky collector

Charts now properly display low toxicity values (0.02-0.05 range)
