feat: revamp portfolio with case studies, curriculo page, and local SEO

Adds dynamic case study and curriculo routes, project health monitoring
for live demo status, and strengthens local SEO (structured data,
service-area targeting for Garuva/Joinville/Curitiba, a dedicated
"criação de sites" service page) so search results better match the
professional title (Engenheiro da Computação) and experience (5 anos).
