ceph: include prodnxsr0014-0019 in public_network

Why: prodnxsr0014-0019 were racked as roles::base but have since joined
the de96a98f ceph cluster as OSD hosts (live enc_role is now
roles::infra::k8s::compute, is_ceph_osd true). Their ceph-public /32s
must appear in public_network on every cluster member, and they must
receive the osd-only ceph.conf.

How:
- Expand profiles::ceph::client::cluster_public_ips from .1-.13 to
  .1-.19 (add ceph-public loopbacks 198.18.23.14-19).
- No role/hiera change needed for 0014-0019: they run
  roles::infra::k8s::compute, already covered by roles/infra/k8s.yaml
  (manage_ceph_conf true, render_mds_config unset/false), so they get
  the [global]-only variant with no mds sections.

Consequence: first convergence now rewrites public_network on the
existing osd hosts (0001-0008) and mon hosts (0009-0013) too, adding
.14-.19; adoption is a single public_network-line change on every
cluster host rather than a no-op on osd hosts. Verified against the
live files: osd (0008) and mon (0009) each differ by exactly the
public_network line, mds formatting on 0009 unchanged.
