feat(exercice): icône d'exercice (ticket #38)

Étend le modèle Drift (tables.dart, app_database.dart/.g.dart), les
entités/use cases/repositories et les écrans bibliothèque d'exercices
et programme pour associer une icône à chaque exercice. flutter
analyze propre, 72/72 tests verts, build APK debug validé. Dernier
ticket du backlog.
