Update the stale pending-suite documentation.

The new It is active, but the enclosing Describe at Line [794] and nearby comments at Lines [787-789] and [917-920] still describe this scenario as pending or as a future PIt conversion. Ginkgo output and source documentation will contradict the active test status. Rename the suite and update the stale comments.

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift

Isolate the multi-PVC setup from the shared CirrOS fixture.

This It inherits the BeforeEach at Lines [827-830], which creates and waits for cirros-test, then creates cirros-multipvc-cbt-test again in its own body. The multi-PVC scenario never uses the first VM. This adds another long VM wait and can fail on an unrelated fixture before the restore starts. Give this case a setup that prepares only the DPA, or move it to a Describe with a case-specific BeforeEach.

Register cleanup for the multi-PVC test.

The suite-level teardown does not delete cirros-multipvc-cbt-restore-backup or cirros-multipvc-cbt-restore-restore. Register cleanup before creating these resources, and delete the restore before the backup while Velero is still running.

Assert both DataDownloads explicitly.

lib.IsRestoreCompletedSuccessfully checks only the Velero Restore phase. Add a bounded assertion that finds exactly two DataDownloads for the restore and checks that both have phase Completed.
