[ci skip] complete NFS CSI migration: complex stacks + platform modules
Migrate remaining multi-volume stacks and all platform modules from
inline NFS volumes to CSI-backed PV/PVC with nfs-truenas StorageClass
(soft,timeo=30,retrans=3 mount options).

Complex stacks: openclaw (4 vols), immich (8 vols), frigate (2 vols),
nextcloud (2 vols + old PV replaced), rybbit (1 vol)

Remaining stacks: affine, ebook2audiobook, f1-stream, osm_routing,
real-estate-crawler

Platform modules: monitoring (prometheus, loki, alertmanager PVs
converted from native NFS to CSI), redis, dbaas, technitium,
headscale, vaultwarden, uptime-kuma, mailserver, infra-maintenance
