hc: consistent striped official-record card + wire past-due overdue variant

- Upgrade the plain teal record banner to the authoritative barber-pole 'Official
  record' banner in the personal/turnover/overdue-personal templates (the switch
  to personal templates had dropped the striped look from live revalidation sends).
- nppes_outdated: replace plain info table with the striped 'Official record -
  NPPES NPI Registry' card (status honestly labeled as our compliance flag).
- Wire revalidation_overdue -> hc_revalidation_overdue_personal.html with a direct
  past-due subject ('Your Medicare revalidation is past due - let's get it filed')
  and PAST DUE status + days-overdue in the record card; due_soon stays warm.
- Striped card now on all 7 templates that show a real record; oig_screening and
  compliance_bundle correctly omit it (no specific record to display).
