- Add secubox-landing script to generate landing pages from HAProxy vhosts - Integrate landing command into secubox CLI - Add boot hook to regenerate landing pages on startup - Fix HAProxy multi-cert SNI using crt-list instead of directory mode - Fix backend IPs from 127.0.0.1 to 192.168.255.1 for LXC compatibility - Auto-convert localhost IPs in RPCD handler and CLI tools Landing page features: - Groups all services by zone with stats header - Shows SSL certificate status per domain - Categorizes by type: Streamlit, Blog, Admin, Media, Dev, etc. - Regenerates at boot (30s after startup) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
