feat(web): foundation com brand JCS + AntD theme + Rafael painel placeholder

- Design tokens (CSS variables) espelhando brand.md v1.0:
  - Paleta JCS Blue #004a99 + estados funcionais
  - Plus Jakarta Sans Variable self-host (LGPD + perf)
  - Radius 12/20, sombra 0 4px 25px rgba(0,0,0,0.05)
  - Layout topbar 80 + sidebar 260 (brand.md canon)
- AntD ConfigProvider com tema JCS (cores, fonts, radius, shadow, motion)
- TanStack Router + Query setup com defaults conservadores
- AppShell desktop (Topbar + Sidebar) com tom canônico
- RafaelPainel placeholder com vocabulário canônico:
  meta de maio, clientes esfriando (OPENFRIOS 47 dias), próxima visita,
  comissão+FLEX, copy direta apple-inspired
- Logos copiadas para apps/web/public/
- Limpeza: removidos placeholders Nx (app.tsx, nx-welcome.tsx, styles.css)
- pt-BR locale (dayjs + AntD)
- Build OK: 878KB JS (vai code-splitar pós cockpits separados)
