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.

Coturn

This folder contains the role to deploy and manage a Coturn service.

Description

Coturn is a free and open-source TURN (Traversal Using Relays around NAT) and STUN (Session Traversal Utilities for NAT) server.
It enables real-time communication (RTC) applications such as WebRTC to work reliably across NATs and firewalls.

Without TURN/STUN, video calls, conferencing, and peer-to-peer connections often fail due to NAT traversal issues.
Coturn solves this by acting as a relay server and/or discovery service for public IP addresses.

Overview

This role deploys Coturn via Docker Compose using the sys-stk-semi-stateless stack.
It automatically configures:

TURN and STUN listening ports
Relay port ranges
TLS certificates (via Let’s Encrypt integration)
Long-term credentials and/or REST API secrets

Typical use cases:

Nextcloud Talk
Jitsi
BigBlueButton
Any WebRTC-based application

Features

Stateless container deployment (no database or persistent volume required)
Automatic TLS handling via sys-stk-front-base
TURN and STUN support over TCP and UDP
Configurable relay port ranges for scaling
Integration into Infinito.Nexus inventory/variable system
