**Describe the solution you'd like**

I'm pretty sure there is an internal endpoint where you can provide a catalog version and it tells you whether a newer version exists, at which point you can download again. We should be able to check that and redownload if necessary.

**Describe alternatives you've considered**

Removing the catalog and downloading fresh.

**Additional context**

N/A

No files or tests are named in the issue. Start by locating the catalog download and version-handling entry points, then determine how the internal version-check endpoint is accessed. Done means an existing catalog is checked for a newer version and redownloaded when one is available.
