- SqlTestFixture: agrega EnsureV016SchemaAsync + seed del permiso catalogo:rubros:gestionar + Rubro_History al TablesToIgnore
- 6 test files con Respawner propio: agrega Rubro_History al TablesToIgnore
- 2 tests con count hardcoded (Permiso/RolPermiso): 24 -> 25 + rename
- 3 Api tests con count hardcoded (Auth/Permisos): 24 -> 25 + rename
