This is a follow-up to #9389 that I missed. We were already separating transit IPs by version in the code before and after the database. This pushes that separation all the way into the database, which will make it easier to implement updates to dual-stack NICs in the public API. Separating them lets clients update the transit IPs for only one version, without some janky read-modify-write code that ensures we don't clobber the transit IPs for the other version.
