The `check_workstation_setup_script` task on `stm-daily-cron` was failing because `setup_clang_config` (which runs `bazel build compiledb`) was executed before creating the Python venv. The bazel wrapper requires Python dependencies like `yaml`, and when the venv doesn't exist, it falls back to system `python3` which lacks `ensurepip` on Ubuntu 22.04 ARM64, creating a broken venv.

*Fix:* Move `setup_clang_config` to run after `setup_mongo_venv` in `etc/set_up_workstation.sh`.

*Caused by:* a044a661b926 (SERVER-126500: Replace poetry with uv)
