Make "Registering of All Segments for a BBox"- feature mag aware (#8082)

* mag register all segments for bbox feature mag aware

* remove console.logs

* add error toasts for missing mag or segmentation layer

* add changelog

* improve changelog

* move line

* bubble up API error to open toast in view

* fix mag-related edge case

* register segments for segmentation layers without volume annotation layers

* add warning toast if segmentation layer isnt editable

 - It is now possible to focus a bounding box in the bounding box tab by clicking its edges in a viewport or via a newly added context menu entry. [#8054](https://github.com/scalableminds/webknossos/pull/8054)
 - Added the option to export nd datasets as ome tiff or tiff stack. Previously, this was only possible for 3d datasets. [#7971](https://github.com/scalableminds/webknossos/pull/7971)
 - Added an assertion to the backend to ensure unique keys in the metadata info of datasets and folders. [#8068](https://github.com/scalableminds/webknossos/issues/8068)
+- The feature to register all segments within a bounding box now takes the current magnification into consideration, e.g. for calculating the volume limit for a bounding box. [#8082](https://github.com/scalableminds/webknossos/pull/8082)
 
 ### Changed
 - Clicking on a bounding box within the bounding box tab centers it within the viewports and focusses it in the list. [#8049](https://github.com/scalableminds/webknossos/pull/8049)
