fix: correct brightness mapping for 0-255 configured light devices

Browse Source 
Removed the erroneous brightness value mapping (1-100 ↔ 0-255) for devices
configured with brightness range [0, 255]. The previous logic incorrectly
assumed these devices actually operated in a 1-100 range, causing inaccurate
brightness values.
