Updated the domains table to reflect that yalarba.ru is now
Nuxt 4 SSR (not static Vue SPA), and the old static path
/usr/share/nginx/yalarba/html no longer exists.
- Deleted main_dc/yalarba/serv_spa/ directory
- No docker-compose.yml changes needed (service was already unused)
- Updated docs references to point to yalarba-nuxt
- docker-compose.yml and nginx configs had no references to serv_spa
