PR description

This pull request makes a targeted change to the logic for retrieving the world state in ParallelBlockTransactionProcessor. The update ensures that the world state is fetched based on the current blockHeader rather than always using the chain head.

World state retrieval logic:

• Updated getWorldState to use the provided blockHeader for world state lookup, removing a restrictive check against the chain head and simplifying the retrieval process.

• Removed the chain-head parent check in getWorldState.
• Switched world state lookup from chainHeadHeader to the provided blockHeader.

The existing tests have been updated, but no new tests have been added to actually test the new behavior. I think we would need those to avoid regressions
