feat(libra): surface voided transactions in standalone history

Voided entries keep their '!' flag and gain a 'voided' tag per the libra
reject convention, so detecting them needs a tag check rather than a new
flag char. Render them inline with the existing 'x'-flag voided styling
(grey XCircle icon, strike-through title/amount, red-tinted Voided badge)
so users like Nancy can see their rejected entries instead of having them
silently disappear from the list.
