Eitan Seri-Levi cfc748309f At the fork transition ensure we build ontop of the correct parent block hash (#9160)
When producing a block at the fork, treat parent payload status as full

I've been testing on kurtosis and this fixes an issue where we cant propose a block at the fork.

This is a screenshot of the fix. The envelope shows missing because we are missing an SSE event, but the envelope is in fact being imported and the chain is progressing just fine
