Backend stability and security improvements: * internal/util/ — common RandomHex helper, removed 3 duplicates * ESL: deduplicated readMessage (locked/unlocked), net.JoinHostPort for IPv6 * AMI: synchronous reconnect() in readEventsLoop, net.JoinHostPort for IPv6 * Auth: /api/auth/refresh accepts Authorization header only (no ?token=) * decodeJSON: http.MaxBytesReader(1<<20) body limit * Trunks: gatewayParams() uses configured ESL.GatewayPrefix * Config: jwt_secret_env env-var fallback * FSCollector: time.After → time.NewTimer with defer Stop * Monitoring: Prometheus counters (route_requests, nodes_total/healthy, uptime) * go fmt pass across all internal/ packages
