fix(ci): restore status-check job removed from CI workflow

The status-check job was accidentally removed from .forgejo/workflows/ci.yml
in the PR branch. This job is required by the integration test
'CI Workflow Has Status Check Job' in robot/ci_nox_validation.robot.

Restored the status-check job from master branch to fix the integration
test failure.
