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.

Let’s Encrypt SSL for Nginx 🔐

Description

Automates obtaining, configuring, and renewing Let’s Encrypt SSL certificates for Nginx with Certbot. Keeps your sites secure with minimal fuss! 🌐

Overview

This Ansible role sets up the necessary Nginx configuration and Certbot integration to:

Redirect HTTP traffic to HTTPS
Serve the ACME challenge for certificate issuance
Apply strong SSL/TLS defaults
Schedule automatic renewals

It’s idempotent: configuration and certificate tasks only run when needed. ✅

Purpose

Ensure all your Nginx-hosted sites use free, trusted SSL certificates from Let’s Encrypt—all managed automatically via Ansible. 🎯

Features

Automatic Certificate Issuance: Uses Certbot’s webroot plugin to request and install certificates. 📜
Nginx Redirect: Creates a temporary HTTP → HTTPS redirect block. ↪️
ACME‐Challenge Handling: Configures /.well-known/acme-challenge/ for Certbot validation. 🔍
Secure SSL Defaults: Includes modern cipher suites, HSTS, OCSP stapling, and session settings. 🔒
Auto‐Renewal: Leverages system scheduling (cron or systemd timer) to renew certs before expiration. 🔄
One‐Time Setup: Tasks guarded by a “run once” fact to avoid re-applying unchanged templates. 🏃‍♂️
