Pointage enregistré et statistiques de présence

Étape 58 : le présent / absent du référent est enregistré sur
l'affectation (Assignment.attendance + heure, migration 0030,
PUT .../assignments/{id}/attendance) au lieu de disparaître au
rechargement.

Étape 59 : section « Présence » de l'écran Statistiques — créneaux en
cours et créneaux terminés, par poste, rafraîchie toutes les 30 s.
