Defaults matchar servern: intern CODE över HTTPS (ssl.enable=true)

- collaboraUrl -> https://code:9980 överallt (config-node, example-flows,
  .env.example, docker-compose.yml, install.sh, resolve_collabora_url);
  http://code:9980 failar när CODE kör SSL
- verifyTls=false är nu ett krav (self-signed internt) i hjälptext/dok
- integrate: connect_nodered_bridge efter container-up (docker network
  connect bridge, ignorerar already connected) + verifiering via
  docker exec curl -sk https://code:9980/hosting/capabilities (HTTP 200)
- Publik URL förblir https://docs.domain.name i docs

docker-compose.yml
