fix: simplify EmployeeQuestionnaireNew to use invite-only flow

- Remove all authentication and org context dependencies
- Simplify component to work only with invite codes from URL
- Remove complex user/employee matching logic
- Keep exact Figma UI components and styling
- Use only submitViaInvite function for API submissions
- Employees never need to log in, only use invite link
