feat(docker): containerize sag24.ru — multi-stage Next.js build + nginx/php-fpm runtime

Single-container approach (nginx + php-fpm 8.3 + supervisord) to match web.hhivp.com
deployment paradigm (host nginx → docker по порту).

- Dockerfile: builder (node:22-alpine npm ci+next build) → runtime (php:8.3-fpm-alpine)
- docker/nginx.conf: serves static from /var/www/sag24.ru/public_html, fastcgi_pass на 127.0.0.1:9000
- docker/supervisord.conf: запускает php-fpm + nginx
- docker-compose.yml: для деплоя на web в /opt/docker/sites/sag24-ru/, mount contact-config.php read-only
- .dockerignore: исключает node_modules/.git/out из контекста

Container exposes :8080 (бесроутовый bind), маппится на host :4070 на web.
Watchtower label включён (auto-deploy на изменения образа в registry).
