fix(tests): consolidar V016 en SqlTestFixture post issue #29

Rebase de CAT-001 sobre main (post #29) requiere:
- EnsureV016SchemaAsync en SqlTestFixture
- Rubro_History en TablesToIgnore central (el commit original b1be4a5 se skipeo por ser obsoleto post consolidacion)
- catalogo:rubros:gestionar en seed canonical de Permiso + RolPermiso admin
- RubroRepositoryTests refactorizado al patron [Collection] + SqlTestFixture
- RubrosControllerTests apunta a TestConnectionStrings.ApiTestDb
- Counts de permisos admin actualizados 24 -> 25 en 5 tests

Verify: App 819/819 + Api 251/251 + vitest 349/349 verde post-rebase.
