[3.9-OP] Enhance On-Premise Deployment and Authentication Support: Improve on-premise deployment, authentication mechanisms, and documentation.

[sedghi]

What feature or change would you like to see made?

• Update and revamp the integration with KeyCloak for authentication, ensuring compatibility with the latest version
• Implement OAuth authentication flows and provide documentation/tutorials for configuring OAuth with keycloak
• Create guides and videos explaining the deployment process for an on-premise OHIF solution
• Evaluate the use of popular DICOM servers like Orthanc for on-premise deployments
• Perform security checks on the docker file and enhancements to ensure the on-premise solution meets necessary security standards

Why should we prioritize this feature?

As OHIF gains more traction and adoption, there is an increasing demand for on-premise deployment options, especially in healthcare and research environments with strict data privacy and security requirements. Prioritizing this feature will enable smoother on-premise installations, secure authentication mechanisms, and comprehensive documentation, ultimately facilitating wider adoption and addressing the needs of a broader user base.
