All hosts had identical nix-command/flakes settings in their

Assign roles to hosts for better organization and filtering:
- ha1: home-automation
- monitoring01, monitoring02: monitoring
- jelly01: media
- nats1: messaging
- http-proxy: proxy
- testvm01-03: test
Also promote kanidm01 and monitoring02 from test to prod tier.

- Remove hosts/template/ (legacy template1) and give each legacy host
its own hardware-configuration.nix copy
- Recreate ns2 using create-host with template2 base
- Add secondary DNS services (NSD + Unbound resolver)
- Configure Vault policy for shared DNS secrets
- Fix create-host IP uniqueness validator to check CIDR notation
(prevents false positives from DNS resolver entries)
