fix(online): validation client online offline-first (ticket #70)

Corrige l'acceptation de partage hors-ligne (acceptShare,
_acceptCachedShareAndQueueAck, _importSharedPayload dans
application/use_cases.dart) : crée bien une copie locale indépendante
avec de nouveaux IDs avant de mettre l'accusé serveur en file
d'attente. Ajuste app_bootstrap.dart, profile_screen.dart et
share_screen.dart en conséquence. flutter pub get OK, dart format
appliqué (aucun changement), analyze propre (mêmes infos
préexistantes), 137/137 tests verts, build APK debug validé. Dernier
ticket du chantier "Ajouter les features serveur au client" (#63,
tickets #64 à #70 tous terminés).
