Fix annotation naming consistency in webhook design

- Changed all examples in Phase 2 and Phase 3 to use correct annotation names
- Fixed: openstack.org/backup → openstack.org/backup-restore
- Fixed: openstack.org/restore-order → openstack.org/backup-restore-order
- Updated Phase 2 backup example to show full namespace backup (no label selector)
- Fixed all table headers from "Backup" to "Restore" for consistency
- Updated PVC label reference to use openstack.org/backup-restore

All annotations now consistently use the openstack.org/backup- prefix.
