k8s/backend.yaml referenced ${BE_IMAGE} but the workflow env
defines ${IMAGE}, causing envsubst to produce an empty image
name (InvalidImageName). Also consolidated the summary table
to single image line since FE/BE are merged.

The k8s/backend.yaml template used BE_-prefixed env vars
(BE_MEMORY_REQUEST, etc.) but the CI workflow outputs them
without the prefix, causing envsubst to produce empty strings
and K8s to reject the deployment.
