fix(commercial) : corrections formulaire client (ajout de bloc, onglet Information)

- Boutons « ajouter » Adresse/RIB desactives tant que le dernier bloc n'est pas valide (predicats isAddressValid/isRibComplete, reutilises par la validation d'onglet).

- Onglet Information : bouton Valider desactive si aucun champ rempli (pas de validation a vide) — creation uniquement, l'edition garde la possibilite de tout vider.

- Onglet Contact accessible des la creation du client (onglet Information facultatif).
