feat(pihole): add knoe.dev GKE service records for LAN split-horizon DNS

Adds dnsmasq address= directives for all active knoe.dev GKE endpoints
so LAN clients (morgana, Pi nodes) resolve them without hitting external DNS.

Records added:
  mcp.0.knoe.dev   → 8.232.93.14    (knoe-mcp GCE LB)
  auth.0.knoe.dev  → 34.36.71.141   (knoe-auth GCE LB)
  api.0.knoe.dev   → 34.120.221.5   (supabase-kong GCE LB)
  db.0.knoe.dev    → 34.120.221.5   (supabase-kong GCE LB)
  app.0.knoe.dev   → 34.120.221.5   (supabase-kong GCE LB)

auth.0.knoe.dev was previously resolving to 34.120.221.5 (wrong — supabase LB)
causing the knoe-auth managed cert to be stuck Provisioning for 20 days.
Correct IP is 34.36.71.141. Also update auth.0.knoe.dev in external DNS
(name.com) to unblock the GCP managed cert.
