TVA par défaut à 10 %, corrige le Montant TTC illisible

- TVA par défaut passe de 0 % à 10 % (taux intermédiaire) pour une
  nouvelle ligne -- la plupart des lignes saisies portent effectivement
  de la TVA.
- Montant TTC (désactivé) était illisible : Chromium affiche le texte
  d'un champ disabled via -webkit-text-fill-color plutôt que color,
  qui restait sur son gris par défaut du navigateur -- quasi invisible
  sur le fond gris de --flform-bg-subtle en mode sombre. Fixé
  explicitement sur les deux thèmes.
