The 'Browse all campaigns' Link on the home page renders an <ArrowRight>
lucide icon next to t('campaigns.home.browseAll'), but the translated
string itself ended in '→' (or '←' for RTL locales), so the button
displayed two arrows. Strip the literal arrow from all 16 locale files
and let the icon do the visual work — it already handles RTL via
rtl:rotate-180 in CampaignsPage.tsx.
