Add co2-density property mapping to SPEC_PROP_TRANS_MAP to enable statistics recording for CO2 sensors. Changes: - Import CONCENTRATION_PARTS_PER_MILLION from homeassistant.const - Add co2-density mapping with: - device_class: SensorDeviceClass.CO2 - state_class: SensorStateClass.MEASUREMENT - unit_of_measurement: CONCENTRATION_PARTS_PER_MILLION (ppm) This ensures CO2 sensors (like those from CGDN1 device) have proper device classification and Home Assistant can record long-term statistics. Fixes XiaoMi#1630

Currently, CO2 sensors (like those from CGDN1/Qingping Air Monitor Lite device) are missing:
state_classattributedevice_classattributeThis prevents Home Assistant from recording long-term statistics for CO2 sensors, while other similar density sensors (PM2.5, PM10, TVOC, VOC) work correctly.
Testing
After applying this fix, CO2 sensor entity shows:
{ "state_class": "measurement", "device_class": "carbon_dioxide", "unit_of_measurement": "ppm" }Home Assistant statistics recording is now enabled for CO2 sensors.
Fixes #1630
