v3 : inertie à cinq crans — interface (L10)

L'inertie se lit en crans, « 3 / 5 · moyenne » (très basse, basse,
moyenne, haute, très haute ; fr, en, es). Le sélecteur offre les cinq
crans, l'actuel marqué ; le changement se vote au cran de l'article.
L'article dit le passé de son inertie (vote ou réglage de départ).

« Réglages de la formule », en lecture seule, depuis l'en-tête du doc et
depuis le vote d'un article (onglet « Réglages » du panneau, dans
l'URL) : W et sa source, C, B, la participation habituelle (médiane ou
référence, sur combien de propositions, quand), et les cinq crans : M,
G, part exigée, voix pour exigées à la participation de la version
regardée (ou habituelle depuis l'en-tête).

Composants à part (InertiaPicker, FormulaSettings), branchés par
quelques lignes dans VoteView. La formule dépliée ne fait plus déborder
le panneau. e2e : C4 (cran de l'article dans la formule), C20 (réglages
et cinq crans), M1 (réglages lisibles sur mobile).
