Replaced all hardcoded service name concatenations with the new get_service_name filter.
This ensures consistency, proper lowercase formatting, and correct handling of '@' suffixed units.
Added unittests for the filter (normal, custom suffix, '@'-units, and lowercase normalization).

- Unified service templates into generic systemctl templates
- Introduced reusable filter plugins for script path handling
- Updated path variables and service/timer definitions
- Migrated roles (backup, cleanup, repair, etc.) to use systemctl role
- Added sys-daemon role for core systemd cleanup
- Simplified timer handling via sys-timer role
Note: This is a large refactor and some errors may still exist. Further testing and adjustments will be needed.
This commit restructures systemctl service definitions and category mappings.
Motivation: Alarm-related bugs revealed inconsistencies in service and role handling.
Preparation step: lays the groundwork for fixing the alarm issues by aligning categories, roles, and service templates.
