Remove FusionHub editor assets and update workspace

Delete unused FusionHub editor images and their .meta files, remove several shaders and test prefabs from Assets, and update .idea/.idea.HALLUCINATE/.idea/workspace.xml (cleanup changelist entries and adjust a workItem duration). Also apply modifications to Assets/Scove/UIScaleTest.unity and Assets/Scripts/UI/UIManager.cs. This cleans up editor-only/unused resources and updates the project workspace to reflect those removals.
