perf(logos): pré-resolver mapeamentos Logo.dev no servidor

Cada EstablishmentLogo dispara um GET para /api/logo/mapping por
nome único (deduplicado pelo React Query, mas ainda N requests por
página). Em /dashboard, /transactions e /payers/[payerId] agora
fazemos uma única query SQL em batch (fetchEstablishmentLogoMap) e
semeamos o cache do React Query antes do primeiro render via novo
LogoPrefetchProvider — eliminando os requests da rede.
