// Fields mirror the /tenders/details/:id response so the tender-details page
// can show them: notice_type_code, form_type, notice_language_code, issue_date,
// issue_time, lots, official_languages. issue_date/issue_time reuse
// unixTimestampFromJson (epoch seconds, tolerant of ms/string) like the other
// timestamp fields. All fields are nullable to stay resilient to partial API
