[Enhancement]: Visibility of AWS unified server snapshots on the dashboard.

### Affected Area

None

### Problem Statement

Server snapshots for unified servers on AWS are currently not visible on the FC dashboard. We do take snapshots regularly; however, their visibility on the dashboard is not available at the moment.

### Proposed Solution

_No response_

No files, tests, or entry points are identified in the issue. First trace how unified-server snapshots are recorded and represented in the dashboard, then define the required behavior and tests; the work is done when AWS unified-server snapshots are visible on the FC dashboard.
