feat: extract Pagination component and use it on all paginated pages

- New lib/components/pagination/pagination.svelte with numbered pages,
  ellipsis for large ranges, and prev/next buttons
- All 6 admin pages (users, articles, videos, recordings, comments,
  queues) now show enumerated page numbers next to the "Showing X–Y of Z"
  label; offset is derived from page number * limit
- Public pages (videos, models, magazine) replace their inline
  totalPages/pageNumbers derived state with the shared component
- Removes ~80 lines of duplicated pagination logic across 9 files
