Resolves the runner Dockerfile to the lint-standard Acquire::Retries=3
and keeps the collabora TODO wording; hardens the merged tree for the
stricter lints (apt retries in the tor Dockerfile, shell-or-true
markers, comment cleanup).

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.

Move `rm -rf /var/lib/apt/lists/*` before `apt-get update` in every
Debian-based Dockerfile so a stale base-image-baked InRelease
(Valid-Until expired) cannot abort the build layer with exit 100. The
trailing rm at end-of-RUN never ran because `apt-get update` aborted
first; the leading rm forces a fresh fetch from the configured source.
Affected: moodle, bridgy-fed, bookwyrm (2 RUN), postmarks, taiga
backend, svc-db-openldap, svc-db-postgres, jenkins, joomla, mediawiki,
odoo, suitecrm (2 RUN), wordpress.
Add tests/lint/docker/dockerfile/test_apt_update_purge_lists.py to
enforce the contract repo-wide: every `RUN` containing `apt-get
update` MUST `rm -rf /var/lib/apt/lists/*` first in the same RUN, and
MUST NOT pass `Acquire::Check-Valid-Until=false` (which would silence
apt's replay-protection rather than refresh the list).
Rename roles/web-app-taiga/templates/Dockerfile.{back,front}.j2 to
Dockerfile.{backend,frontend}.j2 and update the matching tasks/
main.yml template refs.
