Subject: [PATCH] Keep staging website health checks on the serving port

Constraint: The staging website listens on port 4000 while Cloud Run had inherited a stale liveness port.
Rejected: Rely on Terraform to repair the probe | The service lifecycle intentionally ignores probe changes.
Confidence: high
Scope-risk: narrow
Directive: Keep the staging deploy probe aligned with the website container port.
Tested: staging workflow deployment succeeded with liveness on port 4000; git diff --check
Not-tested: Main is not deployed by this staging-only workflow change
