🎨 Major Dashboard Enhancement - Production Ready

## 🚀 Dashboard Improvements

### Overview Page - Enterprise Features
✅ System Health Score (0-100) with circular progress indicator
✅ Live Activity Feed - Real-time request monitoring with pause/resume
✅ Quick Actions Panel - Reload config, export metrics/logs, clear cache
✅ Enhanced stats cards with performance indicators
✅ Request distribution doughnut chart with real data
✅ Backend status monitoring with health indicators

### Metrics Page - Professional Monitoring
✅ Clean 4-section layout (Request/Response/Error/Backend)
✅ Response Time - Shows avg, total requests, total duration
✅ Error Metrics - Smart display (shows "No errors" when clean)
✅ Backend Performance - Per-backend stats with status badges
✅ HTTP Status Code Distribution - Visual cards (200, 404, 500, etc.)
✅ Real-time performance chart with 1m/5m/15m time ranges
✅ Removed clutter - No more bucket/sum spam

### Prometheus Metrics - Full Integration
✅ Added HTTP_STATUS_CODES tracking per status code
✅ Added HTTP_ERRORS_TOTAL counter for 5xx responses
✅ Added HTTP_TIMEOUTS_TOTAL counter
✅ Backend response time tracking per server
✅ Status code increment on every request
✅ Made RequestForwarder.backend_address public for metrics

### Dashboard Parsing & Calculations
✅ Calculate avg_response_time_ms from histogram (seconds → ms)
✅ Calculate requests_per_second from history
✅ Parse status codes: http_status_codes_total{code="200"}
✅ Parse backend metrics per address
✅ Smart error detection and display

### Bug Fixes
✅ Fixed config-api.cjs recursive proxy (9091 → 9090)
✅ Fixed vite.config.js proxy target (9090 → 9091)
✅ Added config-api.cjs to start-all.sh
✅ Fixed cargo build errors (backend_address visibility)
✅ Cleaned up backup files and temp files
✅ Removed .DS_Store files

### Code Quality
✅ All Rust tests passing (24/24)
✅ Cargo build successful
✅ Dashboard components optimized
✅ Clean separation of concerns
✅ Proper error handling

## 📊 Test Results (150+ requests)

```
✅ http_requests_total: 150
✅ http_status_codes_total{code="200"}: 150
✅ backend_response_time_seconds per backend tracked
✅ Health Score: 100/100
✅ Success Rate: 100%
✅ All backends healthy
```

-    '/api': {
-      target: 'http://127.0.0.1:8000',
-      changeOrigin: true,
-      rewrite: (path) => path.replace(/^\/api/, '')
-    }
-  }
-}
-```
-
-### Required RustStrom Endpoints
-
-The dashboard expects these endpoints from RustStrom:
-
-- `GET /metrics` - Prometheus metrics endpoint
-- `GET /config` - Current configuration (optional)
-- `POST /config` - Update configuration (optional)
-- `POST /reload` - Reload configuration (optional)
-

-
-### Adding New Features
-
-1. Create new component in `src/components/`
-2. Add route/tab in `App.vue`
-3. Update navigation in sidebar
-4. Add necessary API calls
-
-## 📝 Notes
-
-- Metrics are stored in memory (last 60 data points = 5 minutes at 5s interval)
-- Backend status is parsed from Prometheus metrics
-- Configuration management requires backend API support
-- Charts use Chart.js with custom dark theme colors
-
-## 🔒 Security
-
-- No authentication implemented (add reverse proxy auth if needed)
-- CORS should be configured on RustStrom backend
-- Use HTTPS in production
-- Consider rate limiting for configuration changes
