security: enforce required API_KEY_HASH_SECRET and migrate keystore password to credential system
Remove default fallback for API_KEY_HASH_SECRET in tenant context middleware and management service, requiring explicit environment variable configuration. Migrate keystore password handling from /etc/aitbc/keystore_password to /etc/aitbc/credentials/keystore_password with 600 permissions. Add load-keystore-secrets.sh pre-start hook and /run/aitbc/secrets/.env environment file to blockchain-node, blockchain
