M3EThemeController class

Manual brightness control for an adaptive M3ETheme root.

When autoTheming is enabled, toggleBrightness inverts relative to the platform brightness instead of locking an absolute override. When autoTheming is off, brightnessOverride takes precedence until followSystem is called.
