• Refactor ProgramCertificate component
• Refactor ProgramCertificateList component
• Refactor logic to display certificates on verifiable credentials tab
• Renamed ProgramCertificateModal component

There are no changes to renderEmpty in your PR, so I'll write here.
I propose to add another version of the text when programs are not enabled on the platform (you can check if they are active in mfe config). If the programs are disabled, display the message “No certificate available. Finish your first course to get a certificate.”, and if they are enabled, display this.

Platform doesn't have any flag (MFE and platform) indicating the programs availability.
If credentials service enabled then programs enabled too
MFE Config:

I'm going to merge it now and propose to enhance the solution later.
