+- feat: lade nur spezifischen Spannungs-/Temperatur-Thunk beim Öffnen des Detailmodals
+
+- Entfernt globale Thunk-Aufrufe für alle Systemwerte bei Zeitraumwechsel
+- Detailansicht lädt nun nur den benötigten Redux-Thunk (z. B. +15V → Channel 108)
+- Zeitraumwechsel im Modal löst gezielt nur den zugehörigen Thunk aus
+- Reduziert unnötige Datenlast und verbessert Performance bei Embedded-Geräten
