hub: jour_fixe_series downgrade fails on MariaDB (blocks the deploy gate)

hub-mariadb is red on main since the jour fixe series migration (runs 41278853040, 41280638391 on fe6f5009; 41281135050 on 1ab41e22): 20261031190604_jour_fixe_series.py:400 'DROP INDEX ix_jour_fixe_series_project_id' fails with 1553 'needed in a foreign key constraint'. MariaDB DDL does not roll back, so the half-done downgrade leaves the shared test database broken: 2749 setup errors with 'Duplicate column name jour_fixe' follow, 2 failed. Fix the downgrade order or use drop_table alone; check the upgrade too. Check the 2 failures once the cascade is gone. Run hub-mariadb on your branch (gh workflow run hub-mariadb.yml -f sha=<sha>) and report the result. The deploy gate requires this workflow green on the candidate.
