"""Tests for BaseDAO soft_delete / hard_delete / delete routing.
Uses a synthetic model + DAO so the routing logic is exercised in
isolation. Concrete entity DAOs (ChartDAO, DashboardDAO, DatasetDAO)
acquire ``SoftDeleteMixin`` via their model classes in the entity-
rollout PRs and cover end-to-end behaviour there.
