Kevin Veen-Birkenbach fff7d261a2 Refactor run-once logic across multiple roles and integrate unified utils/run_once.yml

This commit standardizes all run-once implementations across the following roles:
- desk-git
- dev-fakeroot
- dev-git
- dev-python-yaml
- sys-lock
- sys-svc-certs (wildcard flavor)
- update-apt
- update-pacman
- update-compose
- user-root (moved logic to 01_core.yml + unified run-once handling)
- web-app-matomo
- web-svc-libretranslate

All roles now:
- Use a block guarded by 'run_once_<role>' facts
- Trigger run-once state through utils/run_once.yml
- Optionally disable handler flushing via 'flush_handlers: false'
- Achieve consistent per-host one-time execution semantics

Nginx HTTPS Certificate Retrieval

🔥 Description

This role automates the retrieval of Let's Encrypt SSL/TLS certificates using Certbot for domains served via Nginx. It supports both single-domain and wildcard certificates, and can use either the DNS or webroot ACME challenge methods.

📖 Overview

Designed for Archlinux systems, this role handles issuing certificates per domain and optionally cleans up redundant certificates if wildcard certificates are used. It intelligently decides whether to issue a standard or wildcard certificate based on the domain structure and your configuration.

Key Features

Single Domain and Wildcard Support: Handles both individual domains and wildcard domains (*.example.com).
DNS and Webroot Challenges: Dynamically selects the correct ACME challenge method.
Certificate Renewal Logic: Skips renewal if the certificate is still valid.
Optional Cleanup: Deletes redundant domain certificates when wildcard certificates are used.
Non-Interactive Operation: Fully automated using --non-interactive and --agree-tos.

🎯 Purpose

The Nginx HTTPS Certificate Retrieval role ensures that your Nginx-served domains have valid, automatically issued SSL/TLS certificates, improving web security without manual intervention.

🚀 Features

ACME Challenge Selection: Supports DNS plugins or webroot method automatically.
Wildcard Certificate Management: Issues wildcard certificates when configured, saving effort for subdomain-heavy deployments.
Safe Cleanup: Ensures that no unused certificates are left behind.
Flexible Control: Supports MODE_TEST for staging environment testing and MODE_CLEANUP for cert cleanup operations.
