Mapping in default view config

 ### Added
 - Added the option for the owner to lock explorative annotations. Locked annotations cannot be modified by any user. An annotation can be locked in the annotations table and when viewing the annotation via the navbar dropdown menu. [#7801](https://github.com/scalableminds/webknossos/pull/7801)
+- Added the option to set a default mapping for a dataset in the dataset view configuration. The default mapping is loaded when the dataset is opened and the user / url does not configure something else. [#7858](https://github.com/scalableminds/webknossos/pull/7858)
 - Uploading an annotation into a dataset that it was not created for now also works if the dataset is in a different organization. [#7816](https://github.com/scalableminds/webknossos/pull/7816)
 - When downloading + reuploading an annotation that is based on a segmentation layer with active mapping, that mapping is now still be selected after the reupload. [#7822](https://github.com/scalableminds/webknossos/pull/7822)
 - In the Voxelytics workflow list, the name of the WEBKNOSSOS user who started the job is displayed. [#7794](https://github.com/scalableminds/webknossos/pull/7795)
