Two root causes for Dashboard backends not showing:
1. haproxy.cfg.tpl had no stats socket directive → /run/haproxy/admin.sock
never created → handler got "connection refused" → empty array returned.
Fixed: added stats socket /run/haproxy/admin.sock mode 0660 level admin.
2. safeAt() used i<=0 instead of i<0 → pxname (column 0) always returned ""
→ all backend names were empty in the API response.
After upgrade: HAProxy reload (triggered by any domain/backend save, or
edgeguard-ctl render-config) will create the socket. v1.1.113.
