rock 88234ac927 ci: enable docker build & sha extraction on PRs ...

- Get short SHA on all events (PRs + pushes)
- Registry login on all events
- Build Docker image on all events (validate Dockerfile on PRs)
- Push only on push/workflow_dispatch (not PRs)
- Prune images on all events

This ensures PR builds verify Docker image builds successfully
