fix(ssr): render issues

[daine]

Summary

Fix a render issue on a node that's just a string Found a render issue when I'm using the PhaseBanner inside the Header component

 ⨯ TypeError: Cannot read properties of null (reading 'useContext')

Also found a render issue if you attempted to add a component that uses forwardRefs like the Link component from NextJS. Didn't find a fix for it, but I added the conditional logic to handle it once we have the fix so it's easier to go back to.
