feat(admin): search + pagination on all data-driven tables

- AdminResource: client-side search box (matches across all fields) + 25/page
  pagination with prev/next and a filtered-count footer
- bumped pageSize on server-paged configs (users/blogs/comments/discounts/music/
  fonts/tags) so search/paginate covers the full set
