infra: join ludo-mini to hubris as Homelab cluster node "strong"

Reformatted the ludo-mini workstation to Proxmox VE 9.2.3 and joined it
to hubris's existing single-node "Homelab" cluster (2 nodes, no QDevice
yet). Added a second NVMe as its own LVM-thin pool (ludo-lvm). Renamed
the wiki/inventory identity from ludo-mini to strong to match the OS/
cluster hostname, since bootstrap's client-enrollment lookup depends on
that match. Also regenerated hosts/grimmory.yaml, which was missing from
git despite being referenced by inventory.yaml.

+      hosts/$(hostname).yaml, so a mismatch would break enrollment).
