(bugfix) Enable rsync progress output for live real runs

Default queued and management-command backups to verbose rsync output so live
run views show progress for long-running real backups, matching dry-run
visibility.

Add a quiet-rsync escape hatch for operators who intentionally want less noisy
real-run logs.
