fix(layout): restore Profile root flex:1, harden Settings + ProfileHeader rows

ROOT CAUSE Profile-Page leer: View+ScrollView verloren beide flex:1
(experimentelle Edit). Ohne flex:1 hat root null Höhe → ScrollView
kollabiert → nur ProfileHeader sichtbar, Rest abgeschnitten.

Profile/index.tsx:
- View style={{ flex: 1, backgroundColor: '#ffffff' }} restored
- ScrollView style={{ flex: 1 }} restored
- Debug-Title "Profil DEBUG-23s00" → "Profil"
- Magenta debug-marker entfernt

Settings row (def. flex-row hardening gegen icon-stack-Bug):
- width: '100%' auf Pressable
- flexShrink:0, flexGrow:0 auf icon-Box
- minWidth:0, flexShrink:1 auf text-Container (Pflicht für RN-Wrap)
- numberOfLines={1} auf label + sublabel (verhindert column-illusion bei
  langem text)
- paddingVertical: 12 fuer breathing room

ProfileHeader hint (gleicher Pattern fix):
- width: '100%' + flexShrink:0 auf beide icons
- minWidth:0, flexShrink:1, numberOfLines={2} auf hint-text
- paddingVertical 10→12
