KeyError: 'settings.onOffStatus' when calling climate.set_hvac_mode with version v0.14.0

Hello Andre0512 (or relevant developers),

I am experiencing an issue with the Haier hOn integration, version v0.14.0, when trying to control my Haier air conditioner.
When I attempt to set the HVAC mode (e.g., turn off the AC or change to cool/heat), I receive a KeyError: 'settings.onOffStatus' error.

Environment:

Haier hOn Integration Version: v0.14.0 (as shown in the attached screenshot from HACS)
Home Assistant Core Version: [2025.5.1]
Haier Air Conditioner Model: [AB35S2SC2FA-1]
Haier Air Conditioner Firmware Version: [5.15.0]
Problem Description:
The climate entity for my Haier AC (climate.ced_server_condizionatore) appears correctly in Home Assistant with all standard attributes and modes. However, any attempt to change the HVAC mode via Home Assistant (e.g., calling climate.set_hvac_mode service with hvac_mode: 'off' or any other mode) results in an error.

Steps to Reproduce:

Navigate to Developer Tools > Services in Home Assistant.
Call the climate.set_hvac_mode service.
Select the Haier AC entity (e.g., climate.ced_server_condizionatore).
Set an hvac_mode (e.g., off, cool).
The service call fails, and the error below appears in the logs.

Additional Context:
It seems the integration is trying to access self._device.settings["settings.onOffStatus"] to change the device state, but this key is not found, leading to the KeyError. This might be due to an API change, a specific behavior of my AC model/firmware, or an issue in how the settings are populated.

Thank you for your work on this integration and for any help you can provide.
