Batch type edition

Refs https://redmine.teklia.com/issues/3652

A user should be able to quickly change the type of children elements being displayed.

The main idea is to create a new batch annotation mode that allows selecting a type (from the pre-existing list of types!) and immediately apply it on clicked elements (through a PartialUpdateElement API call).

When the API Call is successful, the element type change must be immediately refelected on the user interface (through the store of course):

• children tree
• details panel (when an updated element is later selected)

I do not have any meaningful suggestion for the icon to use 🤷
