Handle key upload errors and refine tool flow responses

- Introduce error handling for the keys upload process, logging failures to assist with troubleshooting.
- Improve exception handling in the OpenAI class by returning a more informative response based on the exception arguments if available.
- Replace a return statement in the Newroom tool with an exception raise to standardize tool action termination and provide clearer flow control.

Resolves issue with silent key upload failures. Refines response and control flow for better clarity and debugging.
