fix(config): Refactor QBO configuration and schema validation

- Rearranged the QBO configuration parameters in `qbo.ts` for improved readability and consistency.
- Updated the Zod schema to enforce required fields for `QBO_API_URL`, `QBO_CLIENT_ID`, `QBO_CLIENT_SECRET`, and `QBO_COMPANY_ID`, while making `QBO_REFRESH_TOKEN` optional.
- This refactor enhances the clarity of the configuration setup and ensures that essential parameters are validated correctly.

These changes improve the overall structure and usability of the QBO integration configuration.
