ODIN still lists Avangrid rows from April 2026 (ETR April/May) as active on 2026-10-05; parse_odin now counts events whose own ETR passed >24h ago as stale_customers_out, not customers_out, and since/etr come from live events. Puget Sound Energy sends 0001-01-01T00:00:00Z for no ETR; treat as None. Ack dialog now shows a refused enable's error instead of hiding it behind the overlay.
