Improve editing toolbar display for child layers in popup

[arno974]

In a popup, when displaying the children of a parent layer with both a children popup displayed in a compact way and the option to edit the children, the editing toolbar for each child is stacked. This display is not very consistent.

Additionally, a suggestion to save space in edit mode could be to group these buttons into a single button with a dropdown list (https://getbootstrap.com/docs/4.0/components/dropdowns/#menu-items)

Steps to reproduce the issue

1. Add a relation between two layers in QGIS
2. Change the default popup template of the children layer for the compact way template
3. In QGIS Lizmap, enable editing for the children layer
4. In Lizmap Web, click on a parent layer
