/**
 * LightBrightness characteristic handler for the Night Light service.
 * Controls the brightness level of the night light (0-100%).
 *
 * Features:
 * - Non-RGB models: 4 levels (0, 25, 50, 75, 100)
 * - RGB models: Continuous range (39-100%, minimum 40% to keep light on)
 * - Only adjusts brightness if light is already on and target is non-zero
 *
 * Note: Uses cached device state from background polling to avoid slow read warnings.
