Make user bounding boxes and meshes rotate according to current transformations

[MichaelBuessemeyer]

Context

WEBKNOSSOS support layer transformations. However, in case the active volume layer is transformed, the meshes do not transform with it. For consistency, this should be the case. Moreover, the user bounding boxes do not adapt to the currently natively rendered layers transformations like the skeleton layer.

This came up in PR: #8159 (comment)

Expected Behavior

When transformations are configured

• Meshes should rotate together with their respective segmentation layer
• User bounding boxes should rotate according to the currently natively rendered layer just like the skeleton layer.

Current Behavior

The transform settings have no effect to them.

Steps to Reproduce the bug

1. Configure dataset rotation for a dataset (possible after Allow permanent dataset layer rotation in dataset settings #8159 is merged)
2. Create an annotation for the dataset and load meshes and create bounding boxes
3. Toggle the layer transforms and see that the meshes and bounding boxes do not rotate

• ad-hoc meshing sends the transformed coordinates to the backend which does not work
• clicking on a segment in the right sidebar jumps to incorrect position if the segment was registered in another coordinate system
  • segment positions should probably always be stored in an untransformed manner and then transformed when needed (similar to skeleton nodes)
