feat: add Ansible post-provision verification with E2E test fix

- Add TorrustDeploy::Provision::Ansible wrapper class for Ansible operations
- Integrate Ansible verification into provision command (runs parallel to existing SSH verification)
- Add comprehensive Ansible playbook for post-provision verification:
  * SSH connectivity testing
  * Docker installation verification
  * Firewall status checking
  * System facts gathering
- Add unit tests for new Ansible wrapper class
- Fix E2E test TAP parsing issue by capturing command output to prevent Ansible 'ok:' lines from being interpreted as test results
- Remove unused templates/ansible/verify-ssh.yml template
- All tests passing: unit (7 files, 33 tests), integration, container, and E2E
- Maintains backward compatibility with existing SSH verification methods
