Fix Docker Compose configuration and improve service readiness checks

- Fix Keycloak URL to use service name 'keycloak' instead of 'localhost'
  (containers in Docker Compose must use service names to communicate)
- Uncomment and use wait.sh to properly wait for Keycloak to be ready
- Add wait loop for SirixDB server to be ready before running tests
- This should fix CI test failures caused by services not being ready
