Fusion du lot F : objections redit / contredit, coquilles validées par leur auteur, messagerie, délai de 3 jours

Conflits avec B2 : docs.rs garde shown_tally / shown_evaluation et votable ;
proposals.rs sert les totaux montrés et « votable » ; CONTROLES réunit C24
(« faire une objection », le panier par son adresse), C28–C33 et les deux passages.
