Refactor systemctl services and timers

- 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.
