fix(api): project /favorite/getNewReleases envelope to SearchResultsPage

The endpoint returns V2GenericListDto<AlbumDto> which is just
{has_more: bool, items: [...]} — no total/offset/limit. Our caller
wants SearchResultsPage<Album> to stay compatible with the rest of
the album-list flow, so map items through directly and synthesise
total from has_more + items.len() + the offset we asked for.

Endpoint itself returns 200 OK with a real feed now (confirmed in
logs with Godsmack etc. on the test account).
