Overview: at-a-glance markdown (UPS/PDU/hottest temps/fleet count) + Power entities + key-temp history; giant status card dropped. New UPS view (charge+runtime gauges, battery V, 7d charge / 24h V+runtime graphs, unit facts incl. no-input/output-voltage note, UPS automations). Automations moved to own tab with trend sensors. NUT runtime/voltage/ setpoint entities enabled via registry (disabled-by-default). New pfv_ups_runtime_minutes template sensor. https://projects.knownelement.com/issues/344
