infra(sys-service): centralize async control + pre-deploy backup safeguard

Browse Source 
- Added MODE_BACKUP to trigger backup before the rest of the deployment

- sys-ctl-bkp-docker-2-loc: force linear sync and force flush when MODE_BACKUP is true

- Unified name resolution via system_service_name across handlers and tasks

- Introduced system_service_force_linear_sync and system_service_force_flush (rename from system_force_flush)

- Drive async/poll via system_service_async/system_service_poll using omit when disabled

- Propagated per-role overrides (cleanup, repair, cert tasks) for clarity and safety

- Minor formatting and consistency cleanups

Why: Ensure the backup runs before the deployment routine to safeguard data integrity.
