refactor(scribe): normalize ASCII formatting

Remove decorative Unicode banner comments, replace em-dashes with
hyphens across Dockerfile, configs, docs, and one Go log string,
alphabetize the builder-stage yum package list, and drop the
non-standard description/version LABELs from the runtime stage.
