fix(viewport): restore default visual properties on reset in VolumeViewport3D and VolumeViewport

[GhadeerAlbattarni]

Context

This is fixes an issue in ohif #5922

When a user activates the 3D tool (which applies a volume rendering preset such as CT-Bone), zooms in/out, and then clicks Reset, the image reverts to black and white instead of restoring the original 3D color rendering. The same underlying issue may exist in VolumeViewport.

Root cause

Both VolumeViewport3D.resetProperties and VolumeViewport._resetProperties unconditionally called setTransferFunctionNodes with initialTransferFunctionNodes, which wipes the RGB color transfer function back to the default grayscale ramp captured at volume load time, before any preset or colormap was applied.
setTransferFunctionNodes only resets the RGB color function. It does not touch the opacity, gradient opacity, or lighting properties set by a preset. This left the viewport in an inconsistent state: preset opacity/lighting still active, but color rendering in grayscale.

Changes & Results

Replace the unconditional setTransferFunctionNodes call with a check against the configured default properties (getDefaultProperties):

• If the defaults include a preset or colormap, apply them viasetProperties(properties, volumeId, true). This routes through applyPreset, which fully restores the color transfer function, scalar opacity, gradient opacity, interpolation, and lighting — the complete visual state — in a single call. suppressEvents is set to true to avoid duplicate or redundant events since resetProperties fires its own VOI_MODIFIED at the end.
• If no defaults are configured, fall back to the original setTransferFunctionNodes behaviour (no regression).
  The fix is applied to both VolumeViewport3D.resetProperties and VolumeViewport._resetProperties for consistency. For VolumeViewport (MPR), the fallback path means plain CT viewports with no configured defaults behave exactly as before.

After

Testing

1. Open a study and activate the 3D tool
2. Zoom in/out on the viewport
3. Click Reset
4. verify the image correctly restores the 3D color preset

• Also you can apply a different a preset (e.g, CT-AAA2), then click reset.
  Verify that not only the color has been reset to default but also the opacity, shading, and lighting all set to default.

not sure why we are repeating the same thing twice, can you investigate, i remember 3d viewport was extending the volume viewport. worst case we need a refactor

[GhadeerAlbattarni]

I'll check

Thanks @sedghi for your feedback. Both VolumeViewport3D and VolumeViewport extend BaseVolumeViewport directly. So I added a new method on BaseVolumeViewport so that both subclasses can use it.

How about renaming this to _restoreVolumeRenderingDefaults ?

[jbocce]

Just one small naming suggestion. I have tested locally and it looks good. @sedghi do you have anything to add to this PR?
