GRM-14: feat: use click.echo() for user-facing messages with dual logging

- Create ui.py with say() helper that routes messages to both click.echo()
  (console/stdout, user-facing) and logging.getLogger('grm') (file audit trail)
- Update executor.py: replace logger.info() with say() for start, status, done
  messages; use say(level=ERROR, err=True) before raising AnsibleError
- Update report.py: replace logger.info() with say() for operation report lines
- Update all unit tests to patch say() instead of using capsys or get_logger
- Add test_ui.py with coverage for say() calling both click.echo and logging
- 117 tests, 100% coverage, pyright clean, ruff clean
