Kevin Veen-Birkenbach e09f561f0b Refactor run-once orchestration and bootstrap Mailu/Mastodon in a single deploy

- Replace legacy utils/run_once.yml with the new helpers utils/once_flag.yml and utils/once_finalize.yml
- Introduce utils/compose_up.yml to ensure docker-compose stacks are up and to flush handlers safely without coupling to run-once flags
- Migrate all affected roles (desk-*, dev-*, sys-ctl-*, sys-svc-*, web-app-*, web-svc-*, util-*) to the new run-once helpers
- Rework sys-svc-msmtp to auto-load Mailu once per deploy, check reachability, and reuse the running stack instead of requiring multiple playbook passes
- Adjust web-app-mailu to integrate cert deployment, handler flushing, and run-once handling so Mailu is fully initialized in a single deploy
- Improve Matomo, CDN, logout and CSP/health-check related roles to cooperate with the new compose_up / once_* pattern
- Simplify alarm/backup/timer/service orchestration (sys-ctl-alm-*, sys-bkp-provider, sys-timer-cln-bkps, etc.) by moving run-once logic into dedicated 01_core.yml files
- Update integration tests so utils/once_flag.yml and utils/once_finalize.yml are recognised as valid run-once providers, keeping the global run_once_* guarantees consistent
- Align frontend injection and service dependencies so Mastodon- and Mailu-related services can be brought up coherently within a single deployment cycle rather than several iterations

Docker Volumes Health Check

Description

This role detects unused anonymous Docker volumes that are not bound to any running container.
It can optionally exclude specific volumes from the check using a configurable whitelist.

Overview

The role installs a script and a systemd service with a timer to periodically scan for leftover anonymous volumes.
This helps prevent wasted disk space and leftover resources from old deployments.

Purpose

The main purpose of this role is to keep Docker environments clean by identifying and reporting orphaned anonymous volumes.
It supports a whitelist mechanism to avoid alerting on known or intentional volumes.

Features

Anonymous Volume Detection: Identifies volumes with 64-character IDs not attached to any container.
Whitelist Support: Skips volumes listed in DOCKER_WHITELISTET_ANON_VOLUMES.
Bootstrap Volume Exclusion: Ignores known bootstrap volumes (e.g., /var/www/bootstrap).
Systemd Integration: Installs a one-shot service and timer to automate checks.
Alerting Support: Works with the sys-ctl-alm-compose role for failure notifications.
