feat(storage): add local-path-provisioner as the fleet's persistent-storage backend

MinIO deleted the community edition images upstream. Docker Hub reports
{"message":"object not found"} for minio/minio, and an anonymous pull of
quay.io/minio/mc returns HTTP 401. talos-cp-1 dropped the cached image during
the DiskPressure event on 2026-09-22. The tenant pod was recreated on
2026-09-23 and has been in ImagePullBackOff since. MinIO served no traffic for
13 days, which put vault-0 and loki-0 into CrashLoopBackOff and left the
paperless backups stuck.

Pin the tenant image to the digest of the last community release, so a retag or
a deletion on the mirror cannot break the pull again. Repoint the two
quay.io/minio/mc references at the archived Bitnami client image, also by
digest. Alert on ImagePullBackOff and on a pod that stays not ready, because
neither case raised any alert.

Evidence: https://hub.docker.com/v2/repositories/minio/minio/tags -> {"message":"object not found"}
