- #42: Remove hardcoded ENCRYPTION_KEY fallback from config.js,

  validate table names before PRAGMA

  in BEGIN IMMEDIATE TRANSACTION, add atomic balance/stock checks
- #41: Move all secrets from docker-compose.yml to .env file,
  use env_file directive
- #45: Replace MD5 tx_hash with crypto.randomUUID()
- #46: Upgrade KDF from SHA-256 to HKDF for mnemonic encryption,
  add backward compatibility for legacy format
