Textsystem: Bis-Strich mit Leerzeichen (Zahl – Zahl) per Agent-Sweep

562 Ersetzungen in 50 Dateien: Halbgeviertstrich zwischen zwei Ziffern (=
"bis"-Bereich) bekommt Leerzeichen davor/danach (3–4 -> 3 – 4). Regex
/([0-9])\s*–\s*(?=[0-9])/ auf Rohtext (format-erhaltend, CRLF/Einrueckung
unveraendert), Bindestriche in Woertern und Minuszeichen unangetastet, alle
JSON weiter gueltig. Energiemanager-Zeitbloecke sind Display-Labels (kein
Logik-Key) -> safe.
