feat(logo): integração Logo.dev para logos automáticos de estabelecimentos

- Nova tabela `establishment_logos` no schema (userId + nameKey → domain)
- Utilitários: `buildLogoDevUrl`, `toNameKey`, `logoQueryKeys`, `LOGO_DEV_TOKEN`
- `EstablishmentLogo`: exibe logo via Logo.dev com fallback para iniciais; hover mostra ícone de edição
- `EstablishmentLogoPicker`: popover para buscar e fixar domínio Logo.dev por estabelecimento
- API routes: `GET /api/logo/mapping` e `GET /api/logo/search`
- Server actions/queries para persistência do mapeamento por usuário
- CSP: libera `https://img.logo.dev` em `img-src`
- `.env.example`: variáveis `NEXT_PUBLIC_LOGO_DEV_TOKEN` e `LOGO_DEV_SECRET_KEY`
