feat: handle inactive RTs and RTs via PermSet

[dschach]

• Differentiate between active and inactive RTs
• If a Profile has zero Record Types assigned, and PermSets do, the Master RT shows as default when described. So we choose (at random) one of the available record types.
• Record Type picklists now include an option to show all Record Types that are active, with unavailable ones disabled.
