Torjus Håkestad c515a6b4e1 home-assistant: fix zigbee sensor battery reporting ...

WSDCGQ12LM sensors report battery: 0 due to firmware quirk. Override
battery calculation using voltage via homeassistant value_template.

Also adds zigbee_sensor_stale alert for detecting dead sensors regardless
of battery reporting accuracy (1 hour threshold).

Device configuration moved from external devices.yaml to inline NixOS
config for declarative management.
