v1.4 : groupes de destinataires et simplification de l'écran principal

- Nouveau modèle : groupes nommés (famille, amis…) stockés en JSON dans les
  préférences, avec migration automatique de l'ancienne liste de numéros
  vers un groupe « Mes contacts »
- Écran principal : la roue crantée (doublon) disparaît ; la carte du bas
  affiche des puces de sélection du groupe actif + ses numéros, et ouvre
  la gestion des groupes
- Paramètres : nom (enregistré à la saisie) + liste des groupes ; création,
  édition et suppression via boîte de dialogue avec validation des numéros
- Prefs.kt : accès centralisé aux préférences
