Updates

• 🐛 We've improved authentication error handling for more consistent and informative errors across the Assessment API.
• Introduced a new, more specific error code (CANDIDATE_EMAIL_MISSING) for when an assessment order is attempted for a candidate without an email address.
• UKG Pro: The in-app guidance for setting up a fast-track partnership has been updated with new instructions.
• Workday: To prevent errors, assessment orders are now automatically skipped for candidates who do not have an email address in Workday.
