Subject: [PATCH] Fix file upload limit over 2MB in production with HTTPS

- Use printf instead of echo to correctly write php.ini with newlines
  (Alpine ash echo does not interpret \n, leaving the file malformed
  and PHP falling back to its 2MB default)
- Add nginx.conf with client_max_body_size 25M as front-end proxy
- Start nginx on port 8080 via supervisord; move artisan serve to
  internal port 8081 so nginx can proxy requests with proper limits
