fix(wordpress): correct the network-policy claim and make the Velero selector safe
Addresses the automated review on #492.

Blocking: two comments claimed the public/admin split was kept honest by
kubernetes/apps/wordpress/network-policy.yaml. That file does not exist — the
comment was written against the paperless template and never updated once the
namespace policy proved sufficient. The deeper point in the review is the real
one: a paperless-style workload-scoped policy would be a no-op here, because
traefik must reach the pod directly for every public page. The split is
enforced by the Ingress path rules and Authentik, not at the network layer,
and the comment now says so — an auditor looking for a network control would
otherwise have gone hunting for a file that was never there.

Velero: the schedule excluded the database PVC by app.kubernetes.io/instance,
a label the mariadb-operator was only assumed to set. A wrong assumption there
fails silently and sweeps the live database volume into the snapshot. Inverted
to select the content PVC by labels this repo sets on it, the same direction
openbao-daily already uses.

The Service-name assumption flagged as a suggestion is kept: the CRD's separate
primaryService/secondaryService fields indicate the base Service carries the
resource name, and a mismatch fails loudly at pod startup. Written down as a
first-deploy check rather than left implicit.

# Only wp-content is persisted, not the whole docroot. WordPress core comes
# from the pinned image, so upgrading the site means bumping a tag in Git
# rather than clicking "update" in wp-admin — which is the entire point of
# moving off the Hetzner VM, where core was a mutable pile of PHP on disk.
#
# Consequence to be aware of: WordPress's own core updater will fail against
# a read-only core. Plugin and theme installs still work, because those land
# in wp-content.
