fix(litellm): handle AUTH_CHOICE_CANCELLED to retry auth selection

- Add retry loops in configure.gateway-auth and agents.commands.add
- Catch AUTH_CHOICE_CANCELLED error and re-prompt for auth method
- Users can now go back to auth method selection when LiteLLM setup fails
- Import AuthChoice type for proper typing
