With this commit, it is now possible to display sample (fake)
data in empty views, in the hope of easing user onboarding.
This can be enabled (in list and kanban views) with attribute
sample="1" on the arch root element. In this case, if there is
no data to display, sample data will be generated based on
heuristics (depending on field types and names). This can be
used in addition to the no content helper.

Some web actions/controllers/viewsl have been adapted to properly instantiate the
newly refactored control panel and update it accordingly. We needed to adapt the
starting mechanism of actions and controllers to ensure that the control panel
instantiation did not delay the loading of any widget.
