/**
 * GitLab Integration — End-to-End Tests
 *
 * Validates the GitLab SCM connector lifecycle against the real GitLab CE instance:
 *   1. Container health + direct probe
 *   2. Connector CRUD via API (create, test-connection, health, delete)
 *   3. UI: SCM tab shows GitLab row
 *
 * Workaround for "heavy profile": Instead of checking Docker CLI (which may
 * not be available from Playwright workers), we probe GitLab's HTTP endpoint
 * directly. If it responds, the tests run; otherwise they skip gracefully.
