Harden refresh_designs_snapshot.py summary print against None category

The post-write Categories summary crashed with TypeError when any design
had a None category (sorted() can't compare None < str). The snapshot file
itself wrote fine before the crash, but the traceback masked that. Sort
None-last so the summary always prints and real errors stay visible.
