fix(segmentation): restrict overlay segmentation menu to same frame of reference as viewport background display set (#5900)

- Add FrameOfReferenceUID to SEG and RTSTRUCT displaySet in SOP Class Handlers so the FOR is available for filtering
- Sync optimisticOverlayDisplaySets when background display set changes so the overlay menu reflects the correct state after a background switch
- Add FOR matching guard to the hydrate segmentation synchronizer to prevent the hydration synchronizer from blindly mirroring segmentations from a source viewport to a target viewport if their primary Frames of Reference do not align.
- fix segmentation overlay order reversal on viewport re-render
