fix: standardize memory CI workflow to unified pattern

Reference: riotpiao.com action run 496/707

Unified structure:
- test job: all branches + PRs (install Node.js, checkout, cargo test/check)
- build-push job: main push only, depends on test
- Install Node.js before checkout
- Install docker.io only in build-push step
- Proper secrets (FORGEJO_REGISTRY_USER, FORGEJO_REGISTRY_TOKEN)
- Docker login + build + push + prune
