Update device name and details for LEDVANCE light (#5464)

* Update device name and details for LEDVANCE light

Add support for LEDVANCE SMART+ WiFi Planon Magic

Adds a device profile for the LEDVANCE SMART+ WiFi Planon Magic LED panel light.

Tested with local discovery productKey keyj3w8cmutjmwk5.

Working features:
- Switch
- Brightness
- Color temperature, 2700-6500K
- RGB/HSV color
- Countdown timer
- Light pixel count diagnostic sensor

The device is paired through the LEDVANCE SMART+ app, so the product identifier comes from local Tuya discovery productKey instead of Tuya Cloud.

* fix(ledvance_smartwifiplanonmagic_light): naming

- File rename to follow brand_model_type convention
- Top level name should be generic
