Subject: [PATCH] iOS: optimize chapters list to render at current chapter
 instantly

- Added custom init to ChaptersListSheet that sets scrollPosition state before view appears
- Removed onAppear scroll position update (now set in init)
- List renders directly at current chapter position without any scroll animation
- Better performance for books with 1000+ chapters (no initial render + animate delay)
