fix: Library preserves sidebar tree and categorizes by parent_section

- Sidebar data (board._sidebar_data()) no longer overwritten by library content
- New variables: lib_recent, lib_favorites, lib_shared, lib_private
- Pages categorized by parent_section column: Private/Favorites/Shared
- Recents tab shows all non-trashed pages ordered by updated_at
- library.html updated to use lib_* variables instead of sidebar data
- Favorites/Shared tabs hidden when empty (lib_has_favorites/lib_has_shared)
