feat: Update Sablier configs for debian hostname and reorganize .env.example

- Change Traefik configs to use ${SERVER_HOSTNAME} placeholder (defaults to debian)
- Update ez-homelab.sh to replace SERVER_HOSTNAME in config templates
- Set Sablier session duration to 5m for testing (increase to 30m for production)
- Add SERVER_HOSTNAME prompt and saving in setup script
- Reorganize .env.example with better structure and SMTP variables
- Add production guidance comments to docker-compose files
- Intentional SMTP variable redundancy for service flexibility
