[List] interactive: false is hardcoded in className

## Component
List

## Problem
File: List.tsx line 34

Interactive is hardcoded to false in className:
```tsx
const classNames = cn(
    className,
    { gap, shape, variant, interactive: false },  // Always false!
    styles
);
```

But `interactive` prop exists and should be used.

## Suggested Fix
```tsx
{ gap, shape, variant, interactive },
```

## Impact
Bug - interactive prop has no effect
