feat: [#10] enhance development workflow and SSH debugging

- Add auto-approve flags to Makefile commands (apply, apply-minimal, destroy)
- Add new VM management commands: 'make vm-ip' and 'make vm-info'
- Update integration testing guide with manual volume cleanup section (1.4.1)
- Enhance minimal cloud-init configuration with SSH debugging features:
  - Add password authentication support
  - Add explicit SSH daemon configuration
  - Add cloud-init completion tracking files
  - Add SSH service restart commands
- Improve test script error message for libvirtd service

This improves the development experience by eliminating manual confirmation
prompts and providing better debugging tools for SSH connectivity issues.
