-- ─── Lixeira: soft delete em tudo o que é importante ────────────────────────
-- Apagar no backoffice passa a marcar deleted_at (+ quem apagou). O registo
-- fica em Sistema → Lixeira, onde se restaura a qualquer momento e só se
-- elimina de vez depois de 30 dias (regra em config/functions_trash.php, no
-- próprio WHERE do DELETE).
--
-- Só acrescenta colunas e índices. Safe to re-run.

-- Tabelas que já tinham deleted_at: falta saber quem apagou.
