Add "Asset Type" to the EntityFlyout Component

[opauloh]

Motivation

To enhance the usability and informational value of the EntityFlyout component, the "Asset Type" field should be displayed alongside the "Asset Criticality" field. This addition will provide users with quick access to an asset's type, helping them understand the asset's classification without additional navigation.

Definition of Done

• Add a new field "Asset Type" to the EntityFlyout component.
• Display the "Asset Type" value next to the "Asset Criticality" field in the layout.
• Display "Unknown" as the asset when the asset.type field is missing.
• Ensure proper alignment and spacing between "Asset Type" and "Asset Criticality" according to the Figma mocks
• Update the component logic to fetch and display the asset type (asset.type) from the appropriate data source.
• Add unit tests to cover the addition

Out of Scope

• Changes to the source or structure of the data beyond adding the asset.type field.
