Light will not turn on or off from Matter when using custom light modes

This is a bug in Matter integration I discovered yesterday after getting a new RGBICWW strip and using a custom mode, can be replicated in any other WiZ product, bulbs included, as long as a custom mode is active.

**The problem**

Using a custom light mode in a WiZ light makes it ignore on or off commands from Matter. That affects any automation to turn off all the lights since they will stay on or the platform incorrectly will state it is off when in reality it is on.

Tested in current 1.38.0 firmware. Only affects custom modes, predefined dynamic modes behave correctly.

**Steps to reproduce**

1. Create a new custom light mode from the Library section if you don't have any. 2. From WiZ app, for instance, turn on the light by setting the custom created mode or activating a scene that uses that mode. 3. From a smart home platform using Matter integration, try to turn off that light.

The expected outcome is the light turning off, but it will stay on.

The opposite also fails. If the last mode was a custom one and the light is currently off, you cannot turn the light on from Matter with just a "on" command, it will stay off. If you force a specific colour from Matter it will turn on in that colour, but that will exit the custom mode of course.

It's another case of WiZ part of the device and Matter part of the device not sharing the same view of the state of the light and commands not having the desired effect.

P.S: Trying to change the brightness level from Matter also has no effect when a custom mode is active. Just like on/off, it works fine in the predefined dynamic modes so it's specific to custom modes.
