fix(profile/faq): demographics-hint auto-expand + FAQ-chevron-direction

Profile:
- Hint "fuelle deine anonymen Daten aus" oeffnet das DemographicsAccordion
  jetzt automatisch via expanded-Prop + useEffect mit LayoutAnimation.
  Vorher: scrollte hin, liess es geschlossen, User musste nochmal tappen.
- DemographicsAccordion: expanded-Prop fuer external-trigger; interner
  expandedLocal-State, Toggle-Button bleibt unabhaengig functional.

ProtectionDetailsSheet FAQ:
- chevron-forward (0deg→90deg Rotation, sah aus wie Nav-Link) → chevron-down
  (0deg→180deg). Geschlossen=runter, offen=hoch. State-Toggling war schon
  korrekt, nur visuelle Affordance war falsch.
