Andrey Kolkov 1d05dafb2e fix(mongodb): own and prune the system-bucket archive, and heal the restore read path
Two correctness gaps on the useSystemBucket flow.

Retention. Gating spec.backup.tasks out of the chart also dropped the keep
that psmdb task retention used, and an on-demand PerconaServerMongoDBBackup
is not covered by task retention, so nothing pruned the shared cozy-backups
bucket — a retention-swept Plan grew it unboundedly for every tenant at
once. Own the archive the way the Redis/Rabbitmq drivers own theirs: stamp
the operator's percona.com/delete-backup finalizer onto the backups minted
on this flow, and on Cozystack Backup deletion delete that operator CR and
wait for the finalizer to free the object before releasing. A legacy backup
(tenant's own bucket) keeps the pre-existing hands-off no-op. Adds the
delete verb on perconaservermongodbbackups and a skip-artifact-cleanup
escape hatch for a wedged operator, matching the sibling drivers. Also drops
the unused update verb from the psmdb cluster RBAC (server-side apply is a
patch, not an update).

Restore. resolveMongoDBBackupSource returned early off the live operator
Backup CR whenever it reported a destination, copying status.s3 as-is. On
this flow the operator can echo a destination with status.s3 empty (the
storage was injected, not declared), and the target has no declared storage
to resolve from either, so the restore stranded with no coordinates.
Backfill a missing live S3 block from the snapshot the BackupJob recorded.

Also correct the precondition godoc: the pbm agents start on
spec.backup.enabled alone; the declared storage is required by the backup
CR's resolution, not by the agents.
