fix(installer): Correct API client instantiation for validation

This commit resolves a bug where the interactive installer was failing to validate the API key.

The root cause was that the installer was passing the API key as a raw string, while the  constructor expects a configuration object (e.g., ).

This fix corrects the instantiation within  to pass the proper configuration object, ensuring the API key is handled correctly and the validation call succeeds. The client and type definitions have been restored to their stable, correct state.
