Merge pull request #30445 from mantidproject/30433_correct_transform_ellipsoid_when_axes_swap_sliceviewer

Apply correct transform to ellipsoid eigenvectors when axes swapped in sliceviewer

Will make maintanance issue for this - just need to get PR merged

Changed way fake ellipsoid shape made such that bg and peak have same covar matrix and makes test values more transparent.

Eigenvectors were not in columns - only obvious when looking at ellipsoid with axes not aligned with viewing axes.

Merge pull request #30414 from mantidproject/30410_update_EngDiffUI_fit_browser_status_during_sequential_fitting

Update status of fit in fit browser during Sequential Fit in EngDiff UI

Fix error when saving plots with normalisation

Also need to change fake ellisoid so that bg and peak have same eigenvectors...

Previously the transformation determined the order of the eigenvector columns rather than applying the transformation.
