Adds support for useHostNetwork the unity-builder (#828)

* fix: remove concurrency block from reusable workflow to prevent deadlock

When integrity-check.yml calls validate-orchestrator-integration.yml via
workflow_call, both workflows resolve github.workflow to the same name
("Integrity"), creating identical concurrency groups. GitHub detects this
as a deadlock and cancels the run.

Fix: remove concurrency from the reusable workflow entirely — the caller
already manages concurrency for the group.
