[FIX] web: kanban containment

Set up the following kanban columns:

| Col 1 | Col 2 | Col 3 | Col 4 | Col 5 | Col 6 | F |
|       |       |       |       |       |  Card |   |

<------- Screen width ---------->

Col x are unfolded columns.
F is a folded colum.

Moving the Card from Col 6 to F is impossible: the card won't go 'out of
the screen' on the right, which prevents its center to reach F.

Commit 5ba6d93810ba44 deactivates the drag & drop on read-only fields.
In order to restrict the kanban cards displacements, the `containment`
attribute is used to either restrict the displacement:
- in `o_kanban_view` if draggable
- in the parent if not (to allow the resequence)

The class `o_kanban_view` is too restrictive: when movind the card to
the folded column F, the card must go out of `o_kanban_view`.
