qa/cephadm: zap raw devices before OSD deployment

follow up on commit f3c938f5032885434dd2ab77f9b2e6bc05917f3c

```
2026-04-22T10:16:21.350 DEBUG:teuthology.orchestra.run.trial118:> sudo ceph-bluestore-tool zap-device --dev /dev/nvme3n1 --yes-i-really-really-mean-it
2026-04-22T10:16:21.358 INFO:teuthology.orchestra.run.trial118.stderr:sudo: ceph-bluestore-tool: command not found
```

ceph-bluestore-tool is not available on the host and must be run from within a container.

Instead, use `ceph-volume lvm zap` which internally calls `ceph-bluestore-tool zap-device`.
