ESP-Switch v1.1.0 - 12V COM+NC

Use COM + NC wiring: the relay stays released during normal router operation and energizes only for the 10-second power-off window. This release also adds verified HTTP probes, a minimum outage duration, Wi-Fi reconnect grace, retry backoff, and RTC recovery. Rewire from NO to NC before upgrading from v1.0.0. The public firmware uses admin / esp-switch for the web login and esp-switch for the setup access point.
