Feuilles de poste : ajouter la programmation du jour (horaires artistes)

Sous le référent, la liste des artistes qui jouent ce jour-là (heure de
passage + nom), tous postes confondus — repère utile même hors de la
régie (affluence prévisible au bar, sécurité...). Triée par horaire,
omise si aucun artiste ne joue ce jour-là.
