Consolidate BIND DNS into one bind-internal namespace

Reshapes the three DNS tiers from separate ns-* namespaces into a single bind-internal namespace and renames the StatefulSets, and scopes the TSIG keys to their cluster (needs the clusterRef field from operator v0.1.3). - move the 3 clusters + zones + keys into apps/base/bind-internal: BindCluster names bind-authoritative / bind-resolvers / bind-externaldns (= StatefulSet names), LBs kept on .6/.7/.8, external-dns hostnames renamed - add clusterRef to the transfer-key (bind-authoritative) and externaldns-key (bind-externaldns) TSIG keys so they no longer leak across clusters - remove the old ns-auth / ns-resolver / ns-externaldns apps - ApplicationSet + AppProject: replace the three ns-* entries with bind-internal - bump bind-system operator to v0.1.3 (CRD install link + image) so the CRDs understand the new clusterRef field - operator stays in bind-system (unchanged)
