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

# Automated Email Alerts for Service Failures
## Description
This role installs and configures the necessary components for sending email notifications via systemd when a service fails. It sets up the `{{ system_service_id }}` service and configures email parameters and templates using msmtp.
## Overview
Optimized for secure and reliable service failure notifications, this role is an integral part of the overall `sys-ctl-alm-compose` suite. It ensures that, upon failure of a critical service, an email alert is sent automatically to enable prompt troubleshooting.
## Purpose
The primary purpose of this role is to provide a comprehensive solution for automated email notifications in a systemd environment. By integrating with msmtp and customizable templates, it delivers clear and timely alerts about service failures, thereby enhancing system reliability.
## Features
- **Service Installation & Configuration:** Installs msmtp and configures the email sending service.
- **Customizable Templates:** Supports tailoring email templates for service failure notifications.
- **Secure Notifications:** Integrates with systemd to trigger email alerts when services fail.
- **Suite Integration:** Part of the `sys-ctl-alm-compose` suite, offering a unified approach to service failure notifications.
