AstryxShadow class

One shadow layer, as CSS box-shadow describes it.

Flutter's BoxShadow cannot express an inset shadow, and five of Astryx's eight shadow tokens are inset — the focus, selection and validation rings on form controls. Dropping the distinction would silently render those as outer shadows, which is why this type exists rather than BoxShadow alone.

blurRadius is already in Flutter's units. See astryxCssBlurToFlutterRadius for why that is not the CSS number.
