fix(dashboard): graceful error handling for Neo skills when unconfigured

- Add _discover_bay_credentials() auto-discovery in _get_neo_client_config()
- Catch ValueError separately in _with_neo_client(), log at DEBUG instead of
  ERROR with full traceback — prevents log spam when visiting Skills page
  without Bay configured
