- Station.code: usa UniqueConstraint("code", name="uq_stations_code")
esplicito in __table_args__ invece di unique=True sulla colonna,
per allineamento con la migration 002 ed evitare drift Alembic.
- Aggiunge test test_duplicate_assignment_is_rejected per coprire
il vincolo uq_station_recipe (regola business centrale del modello).
- Sposta import IntegrityError a module-level per consistenza.
Feedback da code-reviewer su Task 2.
