ensure fetchServerResponse is a valid record when stored in router cache (vercel#55690)

Since these values are inserted into the cache and read with
`readRecordValue`, they need to have a `status` property otherwise it'll
be re-thrown in `navigate-reducer`. Investigating if this resolves an
issue where under certain circumstances navigations get stuck
suspending.

Closes NEXT-1643
