fix: add TRANSMISSION defaults and curl timeout to production deploy

- Add :-admin defaults for TRANSMISSION_USER/PASS in docker-compose.yml
  to prevent crash on startup when vars are unset
- Add --max-time 10 to registry mirror health check curl to prevent
  2+ minute hang when mirror is unreachable
