feat: control room hero, SEO/AEO optimization and design system fixes

Hero: replace particle field with cobe globe (Capricorn view, multi-axis drag, reduced-motion safe), telemetry HUD with pointer parallax, particle text build effect, Space Grotesk display font. SEO: short titles with template, PT-BR accents, twitter cards on dynamic cases, escaped JSON-LD via lib/jsonld.ts, CSP report-only, 25 service FAQs answer-first. Design: fix TW4 layered reset killing spacing utilities, literal @theme tokens, mobile hero overflow, header overlap, empty case cards. Remove framer-motion (unified on motion/react), header version badge, phone number from hero CTA. Production build verified (24 static pages).
