feat(data): édition ponctuelle des séries en séance (ticket #21)

Étend le modèle Drift (tables.dart, app_database.dart/.g.dart) et la
couche application (entités, use cases, repositories) pour supporter
l'édition ponctuelle des séries pendant l'exécution d'une séance, sans
modifier le modèle/séance-modèle. build_runner OK, flutter analyze
propre, 30/30 tests verts, build APK debug validé.
