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.

unattended_upgrades
Installs and configures unattended-upgrades for automatic security
patching, separate from update-packages.yml (which handles deliberate,
scheduled full-package updates — see the repo README). Security-only by
default. Reboots when required, at a fixed scheduled time (default 03:00),
rather than never or immediately — see defaults/main.yml to change this.
Mail-on-failure is supported but disabled by default since no mail
transport is configured on these hosts yet.
