Need for authentication

[adepauldami]

To enhance the Codepad project, integrating user authentication can significantly improve its functionality by allowing users to:

1. Store Code in the Cloud: Users can securely save their work in the cloud, making it accessible across devices and sessions.
2. Collaborative Editing: Users can share a code link for collaboration, choosing between "view-only" or "edit" access for others.
3. Version Control: Track changes made by collaborators, ensuring code integrity and facilitating teamwork.This would make Codepad more robust for both individual use and team projects.
