fix(models): tolerate missing pagination fields in album page

/album/suggest returns a page with only {limit, items} (no total or
offset). SearchResultsPage required them, so the whole AlbumSuggestResponse
failed to deserialize and the album Suggestions carousel silently never
showed. Default the pagination scalars so only items is required.
