Partner demo cards in section 06 were hardcoded Danish strings, so they
stayed Danish in EN mode. Move name + subtitle into COPY.whitelabel.partners
for both languages and render them via a mapped computed; per-card accent and
the placeholder style remain presentational config in the component.
Also harden PartnerCard's avatar-initial against an empty name to satisfy
noUncheckedIndexedAccess.
