The crypto test PRNG was non-deterministic because setup_random() seeded the state but grant_random_initialize_no_lock() overwrote it with /dev/urandom on the first random call. Calling it before memset ensures the initialized flag is set, preventing the overwrite. Also adds --generate mode to crypto-tests for future vector regeneration, updates checkpoint hashes for multisig_and_checkpoints (height 15) and gen_no_attchments_in_coinbase (height 12), and replaces hardcoded Zano addresses/URLs with Lethean equivalents in manual test scaffolding.
