kea-0/kea-1 crash-looped after the dhcp-system deploy. Two causes:
1) kea-dhcp4 rejected the ntp-servers option (code 42) because DHCP option 42 carries IPv4 addresses only, but the CR supplied rotating pool.ntp.org hostnames.
2) kea-ctrl-agent/dhcp4 rejected the /run/kea unix socket path (kea 2.6.5 permits only /var/run/kea) -- fixed in kea-operator v0.1.1.
- Remove ntpServers from the KeaCluster (not representable via DHCP option 42).
- Bump kea-operator, kea, and kea-api images to v0.1.1 (socket-path fix).

Replaces the isc-dhcpd PXE-boot VM with the kea-operator + an HA kea pair, GitOps-managed. Deploys on a new, unused anycast IP so nothing is cut over yet; the production cutover off the current dhcpd address (198.18.19.18) is a separate later task.
- Add `apps/base/dhcp-system`: namespace, kea-operator RBAC + Deployment (v0.1.0), VPA, and the 4 kea.unkin.net CRDs pulled from the operator repo at tag v0.1.0.
- Add CRs translating the legacy dhcpd config (source: puppet `roles/infra/dhcp/server.yaml`): KeaCluster `kea` (2 replicas, hot-standby HA, main.unkin.net, 1200/86400 leases, AU ntp pool); five KeaSubnets 198.18.13-17.0/24 with .200-.220 pools, gateways .254 except .17->.1, next-server 198.18.19.19; Legacy/UEFI-64 PXE client classes; KeaAPI.
- DHCP-advertised DNS points at the in-cluster bind-resolvers cluster (PureLB 198.18.200.7), not the legacy 198.18.19.15 forwarder.
- Pin the DHCP LoadBalancer Service to the free common-pool IP 198.18.200.10 via PureLB.
- KeaAPI bearer token is operator-generated (no plain Secret committed).
- Commit generated kea.unkin.net JSON schemas for kubeconform; register dhcp-system in the platform ApplicationSet + AppProject.
Client-class object names are lowercased (`legacy`/`uefi-64`) to satisfy RFC1123 since the operator renders the kea class name from metadata.name.
