"""Onglet « Configuration » de la GUI V6 (G3-B).

Édite un :class:`ConfigState` partagé : profil métier, raster burn, NER local,
dossier de sortie. Affiche l'état des managers NER. Les options sensibles ne sont
visibles/éditables qu'en mode admin (``admin_mode.is_admin``). Aucune logique de
détection : on édite seulement l'état lu par l'onglet Utilisation.

Les widgets ne sont créés qu'à l'instanciation (import sûr pour ``--self-test``).
