Rate Limiter Dashboard

React + Vite dashboard for the ratelimit backend. Provides:

• Live KPI cards — Total / Allowed / Denied / Cache Hit Rate
• Real-time chart — requests per second, polled every 1s
• Load Tester — run controlled load against any of the four algorithms from the browser
• Algorithm Comparison — stacked bar chart of allows vs denies per algorithm
• Key Inspector — raw Redis state for any key across all four algorithms, with live watch mode
