Expose hourly energy curve data from gateway endpoint

[oyvindwe]

The /clife-svc/pu/air_duct_energy gateway endpoint returns hourly breakdown data alongside electricTotal, which get_daily_energy_kwh() currently discards.

Available data

{
  "resultData": {
    "electricTotal": 0.0,
    "electricCurve": {"0": "0.00", "1": "0.00", ..., "23": "0.00"},
    "coolingCurve": {"0": "0", ..., "23": "0"},
    "heatingCurve": {"0": "0", ..., "23": "0"},
    "durationTotal": 0,
    "costTotal": "0.00",
    "costCurve": {"0": "0.00", ..., "23": "0.00"}
  }
}

Open questions

• What are the units for cooling/heating curves? Minutes? On/off cycles?
• Is costTotal/costCurve based on a configurable electricity price?
• Is this useful for HA energy dashboard, or only for custom sensors?

HA integration considerations

• HA energy dashboard expects total_increasing state class sensors
• Hourly data could feed statistics or be exposed as attributes
• Polling frequency: consider calling only every Nth poll in the coordinator
