Kevin Veen-Birkenbach 716ebef33b Refactor task includes and update variable handling for Ansible 2.20 migration

This commit updates multiple roles to ensure compatibility with Ansible 2.20.
Several include paths and task-loading mechanisms required adjustments,
as Ansible 2.20 applies stricter evaluation rules for complex Jinja expressions
and no longer resolves certain relative include paths the way Ansible 2.18 did.

Key changes:
- Replaced legacy once_finalize.yml and once_flag.yml with the new structure
  under tasks/utils/once/finalize.yml and tasks/utils/once/flag.yml.
- Updated all include_tasks statements to use 'path_join' with playbook_dir,
  ensuring deterministic and absolute file resolution across roles.
- Fixed all network helper includes by converting direct relative paths such as
  'roles/docker-compose/tasks/utils/network.yml' to proper Jinja-evaluated paths.
- Normalized MATOMO_* variable names for consistency with the updated variable
  scope behavior in Ansible 2.20.
- Removed deprecated patterns that were implicitly supported in Ansible 2.18
  but break under the more strict variable and path resolution model in 2.20.

These changes are part of the full migration step required to ensure the
infinito-nexus roles remain stable, deterministic, and forward-compatible with
Ansible 2.20.

Cleanup Docker Resources

Description

This role performs a complete cleanup of Docker resources by invoking a systemd-managed script. It removes unused Docker images, stopped containers, networks, build cache, and anonymous volumes. The cleanup is fully automated and can run on a schedule or be triggered manually.

Overview

Optimized for maintaining a clean and efficient Docker environment, this role:

Loads and triggers the anonymous volume cleanup role.
Installs a systemd service and timer for Docker pruning.
Deploys a cleanup script that invokes:
- The anonymous volume cleanup service.
- docker system prune -a -f to remove unused Docker resources.
Allows forced execution during maintenance runs (MODE_CLEANUP).

Purpose

The primary purpose of this role is to prevent storage bloat caused by unused Docker images, volumes, and build artifacts. Regular pruning ensures:

Reduced disk usage
Improved system performance
Faster CI/CD and container deployments
More predictable Docker engine behavior

Features

Anonymous Volume Cleanup: Integrates with sys-ctl-cln-anon-volumes to remove stale volumes.
Full Docker Prune: Executes docker system prune -a -f to reclaim space.
Systemd Integration: Registers a systemd unit and timer for automated cleanup.
Scheduled Execution: Runs daily (or as configured) based on SYS_SCHEDULE_CLEANUP_DOCKER.
Force Execution Mode: When MODE_CLEANUP=true, cleanup is executed immediately.
Safe Execution: Includes validation for missing services and Docker availability.

Script Behavior

The cleanup script:

Checks whether the anonymous volume cleanup service is defined and available.
Starts the service if present.
Runs docker system prune -a -f if Docker is installed.
Stops execution immediately on errors (set -e behavior).
