Drag-Griff statt ganzem Element + Uebungs-Reihenfolge beim Start uebernehmen

- Sortieren nur ueber einen kleinen Griff (Punkt-Icon) links im
  Uebungskopf; das ganze Element ist nicht mehr draggable (kein
  versehentliches Ziehen beim Tippen/Auswaehlen)
- Beim Session-Start wird die Uebungs-Reihenfolge der letzten
  abgeschlossenen Session desselben Tags uebernommen (server-seitig in
  create_session, in session.fields.exerciseOrder)
- Tests: 170 Checks gruen (40+18+52+32+28)
