Add CT 101 Caddy security audit findings

Browse source

CRITICAL: RECON backends (8420, 8440) accept direct LAN/Tailscale
connections and trust X-Authentik-Username header unconditionally.
Verified exploitation: contacts read, API keys added via spoofed header.

Root cause: No firewall on RECON VM, services bind 0.0.0.0.
Caddy forward_auth is NOT bypassed - direct backend access is the vector.

P0 remediation: Firewall RECON to accept only from CT 101.
