test_executive: target an archived block in the local replayer checks.

After 3feb9cca2a the no-target `mina-replayer` only replays up to the highest canonical block, which in a short-lived test network is the genesis block; it then emits fewer than 25 "Info" log lines and trips `check_replayer_logs`, failing the payments, zkapps-timing, zkapps-nonce and post-hard-fork `-local` tests. These tests now pass an explicit `~target_state_hash` (a recent proof block, or a best-chain block for zkapps-timing) so the replayer walks a full span.
