🐛 fix: make BDD test server use actual config with environment variables

- Modify createTestConfig to load real config
- Respect DLC_DATABASE_HOST and other environment variables
- Fallback to defaults if config loading fails
- Enable proper database connection configuration
- Fix BDD tests in Docker containers
