refactor: replace verbose flag with Ansible verbosity (-v) flag

- Remove custom 'verbose' parameter from module
- Use Ansible's built-in verbosity setting (module._verbosity)
- Verbose output now shown with -v, -vv, -vvv flags
- Add notes to DOCUMENTATION explaining -v flag usage
- Update all examples to remove verbose: true parameter
- Update all documentation to mention -v flag instead
- Simplifies module interface by leveraging Ansible conventions
