test: dockerized test suite (openldap + redis + test-runner)

docker-compose.test.yml spins up the all-in-one OpenLDAP image, a
standalone Redis, and a test-runner that seeds the test user and runs
jest against them. globalSetup honors REDIS_URL; tests/setup.js
initializes the ORM and flushes test Redis keys before the run.
