[FIX] web: legacy kanbanRecord kinda supports luxon

The new WOWL Kanban view supports that luxon be used in the archs.
Legacy kanban had a similar support but for moment.js

Obviously, new archs can't work with legacy implementation because of this.
This commit aims at providing some sort of hackish support, only valid in
the transition phase.
At least one use case has popped up, that is, when editing such kanban view with Studio.
In that case, there was a crash, which is fixed with this commit.

closes odoo/odoo#103821
