Deleting Fusion Scenarios

[#1]

UI Description:
The current Fusion UI does not prompt for confirmation before deleting a scenario. Additionally, there is no visual indication of which scenario is selected for deletion, and deleted scenarios cannot be restored via the UI.

Why this feature is important:
Accidental deletion of scenarios can result in lost work and require significant time to rebuild. Without a confirmation prompt or a visual highlight, it’s easy to misclick and remove the wrong scenario. Since the UI offers no recovery option, this can lead to irreversible loss.

How this feature would work:
When a user clicks the delete icon for a scenario, a confirmation modal should appear asking, "Are you sure you want to delete this scenario?" The scenario line item should be highlighted when hovered over or selected for deletion, so the user clearly sees which scenario is being targeted. Optionally, an "Undo" notification or a soft-delete feature (trash bin or restore option) would add an extra layer of protection.

Current behavior:
Clicking the delete icon immediately removes the scenario with no warning or visual confirmation of which scenario is being deleted. There is no way to restore a deleted scenario through the UI.
