Add Portainer integration as an optional service

- Updated .env.example to include PORTAINER_HOSTNAME, PORTAINER_USERNAME, PORTAINER_PASSWORD, and PORTAINER_PASSWORD_HASH for configuration.
- Modified Caddyfile to add a reverse proxy for Portainer with basic authentication.
- Enhanced docker-compose.yml to include a new Portainer service and associated volume.
- Updated scripts to generate Portainer credentials and include it in the setup wizard and final report.
- Documented the integration process and reflections in the memory bank for future reference.
