[FIX] website_slides: fix slide.slide category creation from kanban view

This commit fixes an issue that raised an error when trying to create a
slide.slide of type "category" on the slide.slide kanban view.

Since it's not possible to disable the "group creation" on the kanban for a
single filter, we disable it globally.

At the same time, we removed the capability to drag and drop slides in that
view.
It was not very useful and could mess up the records by changing the slide type
without changing the associated data (video link, presentation file, ...).
