Add latest tag to production workflow for non-manual builds

[Copilot]

Production Docker builds triggered by version tags (e.g., v1.0.0) were not pushing to latest, only manual workflow dispatches could set that tag.

Changes

• Added explicit tag configuration to the merge job's metadata action:
  • type=semver,pattern={{version}} — version tag (e.g., 1.0.0)
  • type=semver,pattern={{major}}.{{minor}} — major.minor tag (e.g., 1.0)
  • type=raw,value=latest — always includes latest

- name: Extract metadata (tags, labels) for Docker
  id: meta
  uses: docker/metadata-action@v5
  with:
    images: ${{ env.REGISTRY_IMAGE }}
    tags: |
      type=semver,pattern={{version}}
      type=semver,pattern={{major}}.{{minor}}
      type=raw,value=latest

Manual builds continue to work as before with user-specified tags.

Original prompt

The production workflow build (non develop) needs to also push to the tag latest for non-manual builds.
