rosary: split final prayers into individual bead sections with scroll tracking

Map each ending bead to its corresponding prayer (Gloria/Fatima,
Salve Regina, Schlussgebet, St. Michael, Paternoster, Sign of the Cross),
add scroll-to-top button with action_button styling, and fix SVG scroll
lock to prevent snap-back when scrolling to top.
