Refactor version management: Replace useSaveVersion with useIsComparing across components

- Updated MainScene, SideBarLeft, SideBarRight, Simulations, and CompareLayOut to utilize isComparing state instead of isVersionSaved.
- Adjusted conditional rendering and logic to reflect the new comparison state.
- Introduced SyncCam component to synchronize camera state during comparisons.
- Created useSceneStore to manage camera state with position and target vectors.
- Cleaned up imports and ensured consistent formatting across affected files.
