feat(organizations): parité UX avec Annuaire Membres — filtres statut + grille + swipe

3 fonctionnalités ajoutées pour aligner avec l'UX de l'Annuaire Membres :

1. Filtres par statut (chips) : Tous, Active, En création, Inactive, Suspendue, Dissoute
   Chips horizontaux scrollables sous la barre de recherche, filtre local
   (combiné avec le filtre par type de la TabBar + recherche texte)

2. Vue grille toggle : bouton grid/list dans l'AppBar
   Grid 2 colonnes avec cartes compactes (icône, nom, statut, type, localisation, membres)

3. Swipe actions : swipe DROIT → modifier, swipe GAUCHE → supprimer
   Uniquement pour SuperAdmin/OrgAdmin (canManage=true)
   Background coloré avec icônes + labels
   confirmDismiss retourne false → la carte ne disparaît pas
