Fusion de chantier/acte-certification (lots H et S) dans le lot V : le tampon et ses états, avec le quorum et les Propositions seed

- conflits résolus des deux côtés : kept_params garde le quorum (S) et la part simulée, la version déplacée, le cran d'avant (V) ; proposals.rs garde seedMinimal / seedProposal (S) et tallyPending / tallySimulated / myVoteState (V) ;
- simulation::reexamine juge sur le quorum gardé par l'adoption (params.quorum, à défaut celui de l'article) ;
- l'acte répété n'examine plus une adoption qui tient (params.reexamined) ;
- tests V repris sans texte en vigueur au départ (I1, E1 : la Proposition seed) et sur un quorum 2 (small_web) ; le test overview d'une personne invitée dans Monnaie libre suit la simulation (elle vote, chaîne fermée).
