Add service profiles to docker-compose.yml and implement service selection wizard

- Added profiles for various services in docker-compose.yml to enhance service management.
- Introduced a new interactive wizard script (04_wizard.sh) for user-friendly service selection during installation.
- Updated installation script (install.sh) to incorporate the service selection process.
- Added final report script (06_final_report.sh) to summarize installation steps and provide access credentials.
- Enhanced system preparation script (01_system_preparation.sh) by including 'whiptail' for the wizard functionality.
