fix: standardize poimen-workflows CI to unified pattern

Unified pattern enforced:
- test job: runs on all branches + PRs
- build-push job: only on main push, depends on test
- Proper env vars (GOPRIVATE, REGISTRY, IMAGE)
- Install Node.js before checkout
- Install docker only in build-push
- Docker login + build + push + prune
