feat: add --frontend-server flag for server-side builds

Builds frontend on server (91.98.224.44) instead of locally.
Recommended for low-RAM machines where Vite builds hang.

- Added DEPLOY_FRONTEND_SERVER variable
- Added --frontend-server CLI flag
- Updated --all to use server build by default
- Server build: git pull → pnpm install → pnpm build → rsync to /var/www/

infrastructure/deploy.sh
