ResponsiveDimensions extension

Extension on BuildContext for responsive dimension calculations.

All device detection, scaling, and adaptive values are driven by AdaptiFlowData configuration. When no AdaptiFlow widget is in the tree, sensible defaults are used (matching the original hardcoded values).

Performance: Uses MediaQuery.sizeOf, paddingOf, orientationOf, and viewInsetsOf instead of MediaQuery.of to minimize unnecessary widget rebuilds.
