[IMP] website: open the theme_install_kanban_action in the webclient

Before this commit, the switchTheme option was redirecting the window to
the theme_install_kanban_action url.

After [1] was merged, the editor is instantiated inside the webclient
and the action can now be opened directly from there, without a reload.

For that, the request_save event data can include an 'action' parameter,
which the WysiwygAdapter will use after leaving debug mode to trigger
the action with the action service.
