fix(migration): reorder constraint expansion before backfill UPDATE 

Migration 0005 gagal karena UPDATE state='in_progress' dijalankan
sebelum constraint lama di-drop. Constraint lama (dari 0001) hanya
mengizinkan 'not_started','completed','scored' sehingga 'in_progress'
ditolak PostgreSQL (CheckViolation).

Fix: pindahkan DROP/CREATE constraint ke sebelum blok UPDATE backfill.
