feat(ui): migrate remaining pages to the new shell

Apply the sidebar shell and bold primitives across the rest of the app so
the whole experience shares one visual language:

- Browse/organize: series (keeps stacked-covers/series-card CSS),
  collections (keeps wood-paneling + carousel classes), browse_detail.
- Account/stats: profile + form + modal, progress, analytics (stat-card
  tiles), devices, conflicts (status semantics), queue (status/priority
  badges).
- Admin: admin sidebar restyled with icons, dashboard/users/library/
  processing-issues/settings migrated to .card/.btn/.input primitives.
- Docs/setup/misc: docs (keeps prose/highlight.js), api_explorer, setup
  wizard, unlinked_books, custom_section builder.
- Modals/fragments: collection_modal, collection_rules,
  restore_system_collection_modal, filter_item, book_detail_modals — all
  overlays use --surface-overlay + --shadow-pop.

Every Alpine handler, HTMX attribute, id, name, and data-* is preserved;
only presentation changes.
