Use GetEntitiesForDisplayUseCase in ManageControls

[TimoPtr]

Summary

This PR closes #7181 by replacing the usage of friendly name with the GetEntitiesForDisplayUseCase in ManageControls.

I've added the icon of the Entity in the list too, to be like in the other entity pickers.

Pull request overview

This PR addresses #7181 by switching the Control settings screen to use GetEntitiesForDisplayUseCase for entity display metadata (instead of relying on the friendly name attribute), and aligns the UI with other entity pickers by showing entity icons and richer subtitle information.

Changes:

• Replace entity loading in ManageControlsViewModel with GetEntitiesForDisplayUseCase, excluding hidden entities and sorting by display name.
• Update ManageControlsView to render EntityDisplayItem (icon + subtitle()), removing the old domain-string mapping.
• Add Robolectric coverage for hidden-entity exclusion, sorting, and per-server failure behavior.
