+/// Mirrors `models.BackupConfig`. Used both at node level (`GET /node/backup`)
+/// and per-service (`Service.backup`). `nextRun`/`lastRun` here are
+/// aggregates (earliest/latest) across `targets` — each target now tracks
+/// its own `schedule`/`lastRun`/`nextRun` too. There's no `frequency` field
+/// on the Go side anymore; scheduling moved to a per-target cron `schedule`.
