A transient Debian/Ubuntu mirror fetch aborts a docker build layer with exit 100 (it killed the web-app-nextcloud swarm openldap build while the same image built fine elsewhere). New lint under tests/lint/docker/dockerfile/apt/ flags any RUN with apt-get update/install that omits Acquire::Retries; retrofit all 15 apt Dockerfiles with -o Acquire::Retries=3. Both apt lints move into the apt/ subpackage. dnf retries by default and apk has no equivalent flag, so both stay out of scope.

The curl-timeout lint scanned tasks, templates and .sh scripts but not
Dockerfiles, so four build-time downloads (composer for mediawiki and
joomla, wp-cli for wordpress, the Docker GPG key for svc-runner) could
still hang a build against a silent mirror. Pin --connect-timeout and
--max-time inline (Dockerfiles cannot render the filter) and extend the
lint scope to roles/*/files/**/Dockerfile so future ones are caught.
