fix: consolidate Helm chart release with container image build
Resolve issue #7855 by consolidating the Helm chart release workflow
with the container image build workflow. This ensures perfect alignment:
1. Container images are built and pushed to GHCR
2. Images are copied from GHCR to Docker Hub
3. Helm chart is published only after step 2 completes
Previously, the Helm chart was published immediately on tag push before
images were available in Docker Hub, causing deployment failures.
Changes:
- Added helm-release job to container_release_unified.yml that depends
on copy-to-dockerhub job
- Removed helm_chart_release.yml workflow (consolidated into unified release)
Benefits:
- No race conditions between image push and chart publication
- Users can deploy immediately after release
- Single source of truth for release process
- Clearer job dependencies and execution flow
