Render canonical non-voters in voting reports

Ended Stress Eclipse meeting 8 crashes Møteprotokoll at `/municipalities/6/committees/6/voting_report_full/8` with HTTP 500: `undefined method last_in_chain for Poll::NonVoter` in `app/views/meetings/report/_non_voters.haml:13`. The report still assumes legacy voting-right chain objects while Poll now returns canonical NonVoter values. Update shared voting-report presenters/partials to consume canonical role, absence, and replacement data, with mixed original/deputy and full-turnout coverage.
