Breaking changes

climate: aux_heat support has been removed, as HA started issuing deprecation warnings. Only 3 devices used this, and have had alternative switches since HA removed aux_heat from the UI some time ago. #1784
humidifiers: remove deprecated separate humidity sensors (replaced by humidifier current_humidity attribute)
ZX G30: remove separate buttons (replaced by alarm_control_panel)
Some entity names were standardised for translation #1708. The following could not be handled by migrations:
- light uv_sterilization: converted to switch
- switch indicator, backlight, display: converted to light
- light led: renamed to indicator or default, depending on usage
- Loycco sound nightlight: unnamed light renamed to nightlight
