ScrollSpyController: fix race conditions on rapid and smooth scroll navigation

• Fix rapid clicks leaving stale force-release listeners that caused the active state to fall "one click behind"
• Release force on scrollend instead of first IntersectionObserver callback, preventing intermediate sections from stealing active state during smooth scroll
• Sort passed links by DOM order instead of Set insertion order, fixing incorrect active state with non-contiguous content sections
