We need to ensure that communication between services is secure and that only authorized users can access them.

Acceptance Criteria

• The current Traefik proxy has been replaced with a Service Mesh Ingress Gateway.
• Authentication has been delegated to a Single Sign-On identity provider (Keycloak, Dex, or Red Hat)
• Authorization has been delegated to Service Mesh objects
• All communication between components is encrypted using mutual TLS
• Infrastructure improvements have been implemented to handle increased traffic and scalability
• SSO providers can be plugged in easily at a single point.
