Refactor user onboarding and token management

- Enhanced the `Client` initialization to include `TokenStorage` and configuration parameters.
- Replaced `SaveTokenToFile` with a `Client` method for better encapsulation.
- Improved onboarding flow with project ID verification and API enablement checks.
- Refactored token saving logic to ensure proper handling of directory creation and JSON encoding.
- Removed unused file-related code in `auth.go` for improved maintainability.
