fix: replace broken deploy-release workflow with Tekton status tracker

The old workflow called civitai-deployment/deploy.yml which no longer
exists (migrated to Tekton). Replace with a status poller that watches
the GitHub Deployments API for Tekton pipeline status updates.

Devs get a green/red check on release branch commits. The actual
build/deploy is handled by Tekton on the gpu-fleet cluster.
