RGB MQTT publish sets `color_mode` to `hs` instead of `xy`

What happened?

When I publish an MQTT message with an RGB value, Zigbee2MQTT logs the resulting state as color_mode: hs.

According to the documentation, setting a color through RGB should use color_xy and set color_mode to xy. The current behavior is confusing and makes it difficult to configure RGB reliably for this device.

Device: https://www.zigbee2mqtt.io/devices/EBF_RGB_Zm.html

This is an Awox (EGLO) device. In the native application, both the RGB strip and the main light can be turned on and controlled independently, including RGB colors, without any issues.

What did you expect to happen?

Publishing an RGB value via MQTT should set the device color through color_xy and report color_mode: xy, as described in the documentation.

How to reproduce it (minimal and precise)

1. Publish an MQTT message that sets an RGB value for the device.
2. Check the Zigbee2MQTT log or resulting state.
3. Observe that color_mode is reported as hs instead of xy.

Start by reproducing the RGB MQTT publish on the Awox EBF_RGB_Zm device with Zigbee2MQTT 2.13.0, then compare the resulting state with the documented RGB behavior. Trace the publish handling and resulting color state, and consider the issue done when RGB publishes use color_xy and report color_mode: xy for this device.
