feat(cases): cases de clientes, serviços ligados à prova e SEO por página

Cases da SEV Moda Íntima e da Lavação 047; case no formato cliente, problema, entrega, mídia e contato, com detalhes técnicos recolhidos; sem GitHub, ressalvas e fontes de commit. /cases separa clientes e Laboratório. Serviços mostram o case de cliente certo e o bloco de investimento e prazo só aparece preenchido. Metadata social própria por página, not-found com noindex, sitemap com /ia.
