Six new prodnxsr0014-0019 Dell OptiPlex 3070 hosts were registered on the
legacy cobbler server (profile almalinux9-dell_3070) but the fleet had no
matching bootapi catalog entry, so they would fall to the generic almalinux9
autopart-on-sda path.
- Add catalog/optiplex-3070.yaml: auto-nvme, UEFI-aware, fixed ~31G LVM
- Document the entry in catalog/README.md shipped list and per-model table
