chore: update queue dashboard authentication and improve course component handling

- Replaced email/token-based authentication with HTTP Basic Auth for the queue dashboard in production.
- Updated course components to use courseId instead of courseSlug for better consistency.
- Adjusted role-based security checks to utilize isStudentExperience for conditional rendering.
- Enhanced view-as-student functionality to redirect correctly based on courseId.
