refactor: remove redundant SSH verification methods replaced by Ansible

- Remove _verify_ssh_key_auth() method (replaced by Ansible ping module)
- Remove _show_final_summary() method (replaced by Ansible system facts gathering)
- Remove manual SSH reconnection and Docker/firewall checking logic
- Simplify execute() method flow: cloud-init wait → Ansible verification → done
- Update _run_ansible_verification() to include final completion message
- Remove '(experimental)' label from Ansible verification - it's now the primary method
- Reduces code complexity while maintaining all verification functionality through Ansible
- All tests passing: unit, integration, linting
