fix(catalog): image input default didn't interpolate component.version (v4.0.1)

v4.0.0's image input defaulted to ci-*:$component.version, which GitLab does not interpolate inside a resolved input default -> consumers pulled the literal string and failed. Body-hardcode the image (interpolates) and drop the image input across container/container-sign/vale/registry-cleanup. Remove the container sim that depended on the override. Cuts v4.0.1; consumers re-point @v4.0.0 -> @v4.0.1.
