feat(onglets): add checks to know if onglet is enabled or not

[Vexcited]

For some people, news methods throw an error because the menu is disabled in the instance itself.

We need to implement a way to let developers check it themselves but also add checks in the methods to prevent developers calling those methods without properly checking before-hand.

We can use the listeOnglets (showed) and listeOngletsInvisibles (unshowed) property of the ParametresUtilisateur request.
