Subject: [PATCH] feat(metrics): KISS-styled dashboard with double-buffer
 caching

UI:
- Clean card grid with colored stat values
- Services status bar (HAProxy, WAF, CrowdSec) with glowing dots
- Two-panel layout for WAF/Security and Connections
- Live clock with pulsing indicator
- Proper KissTheme.wrap() integration

Performance:
- Double-buffer cache at /tmp/secubox/metrics-cache.json
- 30s TTL with async background refresh
- Cron job for periodic cache updates
- Instant RPCD response (no computation on request)
