Feature Request: SSO using Himmelblau

### Is your feature request related to a problem? Please describe.

#3699
My origanization use Himmelblau for autenticating and compliance checking with Microsoft Entra ID. I am trying to get SSO to work.
Because I am using Himmelblau, the intune-portal is not installed, however i believe the same DBUS interface is exposed using the himmelblau-broker application.

### Describe the solution you'd like

Use the himmelblau-broker to grab authentication tokens for SSO usage.

### Describe alternatives you've considered

none

### Additional context

_No response_

The issue mentions integrating with the himmelblau-broker for SSO tokens, referencing DBUS interfaces. Start by examining the existing SSO/authentication code in the project, likely around DBUS communication. Look for how intune-portal integration is handled as a reference. Determine what the himmelblau-broker API expects and how to adapt the token retrieval. Testing will involve setting up a Himmelblau environment to verify the new authentication flow works.
