fix: pagination scrambling and scroll + feat: excludePostTypes filter

- Fix duplicate x-for keys causing scrambled pagination numbers on
  interactions page (two '…' entries shared the same key)
- Fix scroll target in goToPage — was using dead closest('[x-show]')
  selector, now scrolls to #webmentions-list
- Add flex-wrap to pagination-links for mobile overflow
- Add excludePostTypes Eleventy filter to exclude post types from
  collections by detecting type from frontmatter properties
- Wire excludePostTypes into recent-posts section via sectionConfig
- Add error/stale data banner to changelog page
