Filled box label for the competence diagrams, hierarchy trees and matrices that define the IMPADY/Gartner visual language. `level` sets fill depth so you can encode a 3-step legend (strong → limited).

```jsx
<InfluenceTag level={1}>Direkter Einfluss</InfluenceTag>
<InfluenceTag level={2}>Sekundär</InfluenceTag>
<InfluenceTag level={3}>Begrenzt</InfluenceTag>
```

`tone` navy (default) or orange. `block` stretches the tag to fill a grid cell.
