Refactor alarm compose service and systemctl templates

- Fixed bug where not both alarm services (email + telegram) were triggered.
- Removed direct OnFailure references for email and telegram,
  now handled by unified compose service.
- Introduced 01_core.yml in sys-ctl-alm-compose to structure
  role execution (subservices → core service → test run).
- Added configurable variables SYSTEMCTL_ALARM_COMPOSER_SUBSERVICES
  and SYSTEMCTL_ALARM_COMPOSER_DUMMY_MESSAGE.
- Replaced dedicated @.service template with generic systemctl template
  using systemctl_tpl_* variables for flexibility.
- Updated script.sh.j2 to collect exit codes and print clear errors.
- Fixed typos and streamlined vars in sys-systemctl.
