WalkthroughAdds GitLab connectivity validation that checks instance URL format, resolves hostnames, and verifies token validity against the GitLab API before storing integration settings. Validates through HTTP 400 responses on failure and supports testability via dependency injection. Changes

In `@components/backend/handlers/gitlab_auth.go`:
- Around line 450-454: The project-scoped handler ConnectGitLab is missing the
GitLab connectivity/auth validation that ConnectGitLabGlobal performs; after
ConnectGitLab's input validation step, call validateGitLabConnectivityFn with
the request context, req.InstanceURL, and req.PersonalAccessToken, and if it
returns an error respond with c.JSON(http.StatusBadRequest, gin.H{"error":
fmt.Sprintf("GitLab connectivity check failed: %v", err)}) and return — mirror
the same logic used in ConnectGitLabGlobal to prevent saving invalid/unreachable
credentials.
