Cloudflared tunnels are no longer used. All traffic now routes through
Cloudflare DNS to Caddy on helsinki-a over Tailscale.
- Remove cloudflared systemd unit files (copenhagen-a, london-b)
- Remove cloudflared from media_stack role and copenhagen-a host_vars
- Remove cloudflared references from services README and host docs
- Remove cloudflared deploy trigger from CI workflow
Live service on london-b stopped and disabled. copenhagen-a was
unreachable but the tunnel is unused regardless.
