feat: Docker images, compose stacks, nginx config, Gitea CI
- site image: multi-stage node build -> unprivileged nginx (non-root, read-only)
- nginx: CSP + security headers, immutable asset caching, revalidated HTML,
canonical trailing slash, preserved /Linkedin 301, legacy-WP 410s, custom 404
- externalise theme-init so CSP uses script-src 'self' (no inline hash)
- prod + dev compose; .env.example; relay Dockerfile fixed (image ships app user)
- Gitea Actions: quality, e2e, lighthouse budgets, relay build, image push on main
- verified: both images build; relay healthz 200; site serves EN/NO with CSP + redirect
