Tutorial: Modal-Felder zentriert scrollen in Schritten 5-10

- _scrollModalTo scrollt Element in die Mitte des sichtbaren Bereichs
- _scrollModalAndReposition repositioniert Bubble nach Scroll
- Alle Modal-Simulationen nutzen zentriertes Scrolling
- Schritt 4+5 nutzen jetzt _scrollModalTo statt manuelles scrollTo
