fix: correct data-testid for VolumeViewer to distinguish 3D from 2D views

Changed VolumeViewer's data-testid from "vtk-view vtk-two-view" to
"vtk-view vtk-volume-view" to properly distinguish it from SliceViewer (2D).
This was causing confusion as both 2D and 3D views had the same testid.

Also updated test helpers to use the corrected, more semantic selectors.
