 * due_day_1 holds an ISO weekday (1 = Lunes … 7 = Domingo).
 *
 * OJO: aunque el Credit se construye con make() (no se persiste), Laravel SÍ
 * persiste las relaciones BelongsTo que CreditFactory declara como factories
 * (company, client, user): expandAttributes() les hace create(). Sin
 * DatabaseTransactions esas filas quedaban committeadas para siempre — 45 por
 * corrida — y en el CI (BD limpia) terminaban chocando contra el
 * `faker->unique()->safeEmail()` de UserFactory, cuyo registro de unicidad se
 * reinicia en cada test al reconstruirse la app.
