fix: drop lan-only ipAllowList (klipper-lb SNATs all LB traffic to 10.42.0.1, so Traefik never sees real client IPs)

Internal-only for argocd/auth/adguard.labzand.com is now enforced at DNS level:
cloudflare-ddns only publishes ns.labzand.com; internal names resolve solely via
AdGuard rewrites. Delete the *.labzand.com A record in Cloudflare once.
