Use Concurrent Collaborator Licenses as an automatic fall-back when no other license is available

To allow for a graceful degradation of services, users who are allotted to use a Concurrent (Basic/Full) license but can't log in because the license pool is full should automatically get a login done with Collaborator license so they can at least have read only access.

This also serves as a graceful reminder that more full licenses are likely needed without impacting the use of the system much.

This functionality could be included in the Manage Licensing app that has support for CodeBeamer as of June 2025.
