Add expandable rating history charts with interactive tooltips
- Implement clickable player rows to expand/collapse rating history - Add rating history scraping from PDGA history pages - Create custom SVG line charts showing rating progression over time - Add interactive tooltips with date and rating on hover - Include visual highlights when hovering over data points - Implement anti-flicker tooltip system with delayed hiding - Add large hover areas (12px radius) for better user experience - Show grid lines, axis labels, and responsive chart scaling - Cache rating history data to avoid repeated API calls 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
