Make voting-right restoration remove the active replacement

Meeting 11 Chrome acceptance removed C05’s voting right and assigned D02, then repeatedly used “Gjenopprett stemmerett.” The control appeared to submit, but secretary Participants still showed C05 replaced by D02 through meeting end. Final roll call then included C05 and omitted D02, while public history recorded the replacement interval. Restoration must atomically close/remove the canonical replacement, restore the original holder, update attendance presentation, and broadcast all participant summaries. Surface a conflict if restoration cannot apply instead of silently retaining replacement state. Cover restore with vacancy, full replacement, and active-poll guard.
