fix(chain): prevent `merge_chains` from replacing the genesis block

Other code paths (`disconnect_from`, `CheckPoint::insert`) already
protect height 0 from modification, but `merge_chains` allowed an
update chain with a different genesis hash to silently replace the
wallet's existing genesis block. Return `CannotConnectError` when the
update attempts to change the block hash at height 0.
