Rename Popular/HasPopular → Latest/HasLatest in digest ts/mjml/render-preview

The buildParameters function returns events sorted newest-first
(sortBy created_at, slice(0,100)), and the mjml section is already
labeled 'Latest Activity'. The object keys Popular/HasPopular no
longer reflect the semantics, so rename them to Latest/HasLatest.
