Description
Challenge optimistic zk proposals if they are still unsafe. This ensures the game can't resolve as valid and then later have the unsafe chain re-orged out. While the data still may not have been submitted before the game's L1 head, if the safe head has since advanced we know that the data is on L1 and that is the output root that will be derived so there's we don't waste capital by placing a challenge. This also avoids the need to use the safe head db.
Also adds the proposal status to the in progress game info log.
Tests
Added unit test.
