Regular playbooks now use state: present, so they no longer upgrade
packages as a side effect. This adds two separate, explicit mechanisms
to keep the fleet patched instead:
- update-packages.yml: ad hoc / to-be-scheduled fleet-wide upgrade
(safe by default, dist available via -e), plus
update-packages-pinned-example.yml as a template for pinning or
bumping a single package outside that.
- roles/unattended_upgrades: automatic security-only patching via
unattended-upgrades, with a scheduled reboot window and mail
left disabled pending a configured MTA. Applied to every host in
full.yml and server.yml.
Also removes a leftover `upgrade: yes` apt task from pi_standard_setup
and server_basic_environment that was still doing a full upgrade on
every routine run, defeating the point of the state: present switch.
