feat(wazuh): Add LuCI dashboard for Wazuh SIEM integration
Create luci-app-wazuh package with unified security monitoring dashboard
inspired by SysWarden's layered defense model:
- 4 views: Overview, Alerts, File Integrity, Agents
- RPCD handler with 12 API methods for status, alerts, FIM, agent control
- SysWarden-style 4-layer security visualization:
- Layer 1: Vortex Firewall + nftables (kernel-level)
- Layer 2: CrowdSec + Bouncer (IPS)
- Layer 3: Wazuh Manager (SIEM/XDR)
- Layer 4: mitmproxy + HAProxy (WAF)
- CrowdSec integration for threat correlation
- Real-time polling and auto-refresh
- Simplified printf-based JSON output (avoids jshn segfault)
