feat (rgbcw_lightbulb): add Cree CMA21-100W-AL-9ACK (#4501)
Why
===
The Cree Connected Max A21 100W smart bulb (https://www.lowes.com/pd/5001171499) uses Tuya and matches the `rgbcw_lightbulb` config but has no product ID entry, so it falls back to DPS-based matching and incorrectly matches `calex_s45cleare27_light` at 88%.
How
===
The product ID `e8dhekwuvrdogter` was obtained from the Tuya IoT Platform cloud API (`/v2.0/cloud/thing/batch`) and confirmed with `tinytuya scan`, which reported the device as v3.3 at the same address and device ID.
The device reports DPs 20, 21, 22, 23, 24, 25, 26, and 41, which match the `rgbcw_lightbulb` config (DPs 20–28, 30–32, 34). The instruction set from the Tuya IoT Platform confirms the standard RGBCW schema: `switch_led`, `work_mode` (white/colour/scene/music), `bright_value_v2` (10–1000), `temp_value_v2` (0–1000), `colour_data_v2` (HSV), `scene_data_v2`, `countdown_1`, `music_data`, `control_data`, `rhythm_mode`, `sleep_mode`, and `wakeup_mode`.
Test Plan
===
Configured the device in tuya-local with protocol version 3.3 and type `rgbcw_lightbulb`. The device connects and I can control the bulb.
