Fix cla-check job not reporting status in merge queue

The cla.yml workflow had two separate jobs with different names:
- merge-queue-pass: ran in merge queue
- cla-check: ran for PRs only

When branch protection requires 'cla-check' to pass, the merge queue
would wait indefinitely because only 'merge-queue-pass' was being
reported as a status, not 'cla-check'.

Consolidate into a single 'cla-check' job that runs for all event
types, using step-level conditions to skip the actual CLA work in
merge queue context (since CLA is already verified at PR time).
