rosary: add mystery images with scrollable sticky column and mobile PiP

Add a third grid column for sorrowful mystery images (mocking for
mysteries 2-3, crucifixion for mystery 5). Desktop uses a scrollable
sticky sidebar synced to prayer scroll position. Mobile shows a
floating PiP thumbnail. Extract prayer page PiP logic into reusable
StickyImage component.
