Rend les plages horaires configurables par utilisateur plutôt que globalement

Chaque compte a désormais son propre data/users/<user>/plages.json, réglable
depuis une nouvelle carte "Plages horaires" sur /settings (avec validation
HH:MM et ordre matin < aprem). Le calcul, les stats de conformité et les
avertissements de saisie lisent la config de l'utilisateur courant au lieu
du plages global. La valeur globale de data/config.json reste lue comme
valeur de repli tant qu'un utilisateur n'a rien personnalisé.
