Reconcile final attendance reports with canonical timelines

Meetings 11, 14, and 15 exposed cross-view report drift. Public attendance correctly recorded ongoing C03→D02 and partial C14/C19→D10/D13 intervals, while final Oppropsliste/Fraværsprotokoll omitted active deputies or listed original councillors; in meeting 11 secretary Participants, public history, and final roll call each disagreed. Route final roll call, absence, replacement, compensation, protocol, and public attendance through the same canonical effective participation timeline and define boundary semantics at meeting end. Add full, partial, ongoing mid-meeting replacement, restoration, and vacant-seat coverage with cross-report invariants.
