T1M (CL-L02D) RGB effects fail with UNSUPPORTED_CLUSTER manuSpecificLumi (regression since 2.9.1)

What happened?

What happened?
Setting effect/effect_speed/effect_colors on the Aqara T1M Ceiling Light (CL-L02D) fails with:

z2m: Publish 'set' 'effect' to '<friendly_name>' failed: 'Error: Status 'UNSUPPORTED_CLUSTER' manuSpecificLumi'

Same happens for effect_speed and effect_colors. Payload format matches the official docs exactly (https://www.zigbee2mqtt.io/devices/CL-L02D.html).

Device firmware: 27 (meets documented minimum requirement)
Zigbee2MQTT version: 2.13.0

Confirmed by another user with the same error and firmware/z2m version combo, who found that downgrading to Zigbee2MQTT 2.9.1 resolves the issue:
https://community.home-assistant.io/t/aqara-advanced-lighting-custom-integration/969960/44

This suggests a regression was introduced somewhere between 2.9.1 and 2.13.0 affecting writes to the manuSpecificLumi cluster for T1M RGB effects specifically.

What did you expect to happen?
Effect commands should be accepted by the device as documented.

What did you expect to happen?

effect shall be executed

Notes

No response

No source file or test is identified. Start by reproducing the effect, effect_speed, and effect_colors writes for the Aqara CL-L02D on Zigbee2MQTT 2.13.0, then compare the manuSpecificLumi handling with 2.9.1. Done means the documented commands are accepted without UNSUPPORTED_CLUSTER.
