fix: Arabic STT + DM scroll + info sheet FormSheet

STT (Arabic):
- Deepgram hat nova-2-general ar/tr-Support eingestellt (400 Bad Request)
- Fix: einheitlich nova-3 für alle Sprachen inkl. ar/tr
- Stale Kommentar aus 2026-05-30 entfernt

DM scroll-to-bottom:
- onLayout auf FlatList hinzugefügt → zusätzlicher scrollToEnd nach
  initialem Layout-Pass (Android-specific race condition)
- onOpenImage im FlatList-Renderer auf Lightbox verdrahtet (war () => {})

Info-Sheet:
- Modal(pageSheet) → FormSheet mit initialHeightPct={0.85}
- Nutzt jetzt unsere eigene Sheet-Komponente konsistent
