fix: remove container override, install deps in workflow steps

Container override breaks docker socket access to dind sidecar.

Changes:
- Remove 'container: image: golang:1.26-bookworm'
- Install Node.js before checkout (required by actions runtime)
- Install docker.io in build step (required for docker build/push)

Now works with shared docker socket via dind sidecar.
