New luci-app-metrics-dashboard with real-time system overview:
- System uptime, memory, load stats
- Core services status (HAProxy, mitmproxy, CrowdSec)
- vHosts, MetaBlog sites, Streamlit apps counts
- WAF alerts, bans, threats statistics
- Active connections (HTTP, HTTPS, SSH, TCP total)
- SSL certificates list
- Auto-refresh every 5 seconds
WAF Filters page:
- Changed stats display to single-line compact format
- Shows "17 Categories · 17 Active · 150 Rules" inline
