Add an RPZ blocklist on the Unbound resolvers that returns NXDOMAIN for a
set of domains (and subdomains) and logs only those matches under rpz-log
tag "blocklist". Domains are templated from resolver_blocked_domains
(single source of truth) into /etc/unbound/blocklist.rpz; respip module
enabled for RPZ support.
Fix deprecation warnings across the Ansible tree:
- apt_repository -> deb822_repository (monitor, aprsc, uisp, grafana),
removing stale .list files and adding update_cache where deb822 drops it
- community.mysql.* -> ansible.mysql.* (monitor) and requirements.yml
- top-level facts -> ansible_facts[...] (ansible_os_family,
distribution_release, fqdn, architecture, default_ipv4) repo-wide
- Add |default() fallbacks for ntpserver, template_run_date,
deb_mirror, and sshd.* to prevent template crash
- Remove include_role: name=alpine from base tasks (no such role)
- Fix SSH -t flag placement in Makefile reboot targets
- Update findings.md
