"""Environment-driven configuration shared by tests and harness helpers.

Every value here can be overridden via env var; the defaults match the ports
documented in the project READMEs (gateway 8000, ledger..notifier 8001-8005,
postgres 5432, redis 6379). No test file should hardcode a port or DSN --
import it from here instead.
