Subject: [PATCH 1/2] feat: added night_mode capability and flow card

Since the Yeelight ceiling light has a night mode using the 'mode' argument of the set_power command (see https://www.yeelight.com/download/Yeelight_Inter-Operation_Spec.pdf) I added a flow card for 'ceiling' lights to switch between Night mode and CT mode.

Subject: [PATCH 2/2] fix: added implicit night_mode toggle on
 light_temperature change

For now I cannot get light_temperature to work on my ceiling light and the default light_temperature change will always toggle the lamp to the normal mode. Therefore I added a setCapabilityValue to onCapabilityLightTemperature.
