ci: fix debug output steps to show full file contents

- Capture kitchen.log before running kitchen diagnose to avoid truncation
- Use cat instead of tail/head to show complete file contents
- Fix client.rb search path to /home/runner/.dokken/kitchen_sandbox
  where dokken stores the generated sandbox files
- Capture all per-instance logs from .kitchen/logs/*.log, not just kitchen.log
