Fix test failure for test_cli_all_flag_lists_configs by ensuring
api/configs_repo submodule is initialized during checkout.
The test expects configs in api/configs_repo/official/ but the
submodule was not being initialized, causing the directory to be
empty and the test to fail.
Related:
- Commit 1cbb8fe: Added api/configs_repo as git submodule
- Commit f5f37f6: Updated render.yaml for Render deployment
This completes the submodule integration for both:
- Production (Render API deployment)
- CI/CD (GitHub Actions tests)
