feat(stellungnahme): KI-Prompt, editierbarer Text, Stepper-Füllstand, DnD-Reihenfolge

- KI-Prompt kopieren mit Ton/Haltung-Slidern und persönlichem Hinweis
- Output-Textarea editierbar (field-sizing: content, auto-height)
- Stepper zeigt Füllstand: Haken (komplett), gelb (leer), grau (unbesucht)
- Weiter-Buttons mit Tooltips bei leerem Schritt
- Auto-Generate beim Betreten von Step 4, live bei Eingabe-Änderungen
- Drag & Drop Umsortierung der Argumente in Step 4
- Step in localStorage persistiert (HMR-Fix)
