verify-backup-server

Enforces backup retention policies by removing old backups

This task verifies that the backup server has proper connectivity to all backup runner machines.

The task performs the following checks: 1. Gets the list of backup runner machines from backup/backup-runner-machine-uuids 2. For each runner, checks if there is at least one active connection 3. If ANY runner lacks connections, disables work order mode and exits 4. If ALL runners have connections, sets backup/backup-server-state to "ready" and enables work order mode

This task should be run to verify backup server readiness after restore agents setup.
