feat: SEO optimization and dynamic jobs API integration

Backend:
- Add Swagger annotations to all job handlers (GET, POST, PUT, DELETE)
- Clean up job handler code

Frontend:
- Expand api.ts with ApiJob types, pagination, and transform function
- Update footer with 'Vagas por Tecnologia' SEO links
- Add robots.txt with crawler directives
- Add sitemap.xml with main pages and job URLs
- Change branding to GoHorse Jobs
