Fixed color temp commands

[harrismck]

Replaced now deprecated 'color_temp' (mireds) HA attribute with 'color_temp_kelvin'.
This fixed color temp commands failing with errors like this:

appdaemon  | 2026-05-12 01:51:02.097131 WARNING HASS: Error with websocket result: invalid_format: extra keys not allowed @ data['color_temp']: request={'type': 'call_service', 'domain': 'light', 'service': 'turn_on', 'service_data': {'color_temp': 337}, 'target': {'entity_id': 'light.my_light'}, 'id': 7}

This is a bit of a bandaid fix, I just know it worked for me and figured I should share.
Fixes #1349
