feat(online): partage client - use cases, inbox cache et import local (ticket #66)

Ajoute l'adapter API distant de partage (infrastructure/remote/share_api.dart)
et les use cases associés (application/use_cases.dart), avec cache
d'inbox et import local des ressources partagées acceptées. Étend le
modèle Drift (migration schemaVersion 11→12) et les entités du domaine
en conséquence. flutter pub get OK, build_runner OK, dart format
appliqué, analyze propre (mêmes infos préexistantes), 124/124 tests
verts, build APK debug validé.
