Create the component a registration names, whichever source it came from.
A compiled registration carries its own constructor. A metadata row carries a component
id instead, and renders through the generic React host. Both are BaseFormPanels once
mounted, so every caller downstream treats them the same.
Returns null when a compiled registration has no constructor, which is a broken
registration rather than an empty slot, so it is logged.
