Kevin Veen-Birkenbach 26b392ea76 refactor!: replace sys-systemctl with sys-service, add sys-daemon, and rename systemctl_* → system_service_* across repo

- Swap role includes: sys-systemctl → sys-service in all roles
- Rename variables everywhere: systemctl_* → system_service_* (incl. systemctl_id → system_service_id)
- Templates: ExecStart now uses {{ system_service_script_exec }}; add optional RuntimeMaxSec via SYS_SERVICE_DEFAULT_RUNTIME
- Move SYS_SERVICE defaults into roles/sys-service/defaults (remove SYS_SERVICE_ALL_ENABLED & SYS_SERVICE_DEFAULT_STATE from group_vars/07_services.yml)
- Tidy group_vars/all/08_timer.yml formatting
- Introduce roles/sys-daemon:
  - default manager timeouts (timeouts.conf)
  - optional purge of /etc/systemd/system.conf.d
  - validation via systemd-analyze verify
  - handlers for daemon-reload & daemon-reexec
- Refactor sys-timer to system_service_* variables (docs and templates updated)
- Move filter_plugins/filetype.py under sys-service
- Update meta/README to point to official systemd docs
- Touch many roles (backup/cleanup/health/repair/certs/nginx/csp/wireguard/ssd-hdd/keyboard/update-docker/alarm compose/email/telegram/etc.) to new naming

BREAKING CHANGE:
- Role path/name change: use `sys-service` instead of `sys-systemctl`
- All `systemctl_*` vars are now `system_service_*` (e.g., on_calendar, state, timer_enabled, script_exec, id)
- If you have custom templates, adopt RuntimeMaxSec and new variable names

Refactor systemctl services and timers

Docker Container Health Check

Description

This role monitors the health status of Docker containers on the system. It detects containers that are either unhealthy or have exited with a non-zero code, and triggers alerts if issues are found.

Overview

The role installs a health check script along with a systemd service and timer to run these checks at scheduled intervals.
If unhealthy or failed containers are detected, the configured failure notifier (via sys-ctl-alm-compose) is triggered.

Purpose

The primary purpose of this role is to ensure that Docker-based services remain operational. By automatically monitoring container health, it enables administrators to react quickly to failures, reducing downtime and preventing unnoticed service degradation.

Features

Automated Health Checks: Detects containers in unhealthy state or exited with non-zero exit codes.
Systemd Integration: Installs a one-shot service and timer to run health checks on a schedule.
Alerting Support: Works with the sys-ctl-alm-compose role for failure notifications.
Configurable Script Location: Controlled via the PATH_ADMINISTRATOR_SCRIPTS variable.
