Subject: [PATCH 2/2] fix: relabel average_power_consumption sensor as range
 efficiency factor (%)

The averPowerConsumption field from the Smart API is not a power value
in Watts but a range correction/efficiency factor in percent. This
change:
- Removes device_class=POWER and the W unit
- Sets native_unit_of_measurement to %
- Updates the icon to mdi:gauge
- Removes the sign-inversion logic (not needed for an efficiency %)
- Updates EN and DE translations

Closes #436
