chore(infra): Follow the DC to office host moves

magrathea, caveman, nikola and frootmig moved from kosherinata (DC) to
hanzalova (office) on 2026-11-01 and were renamed accordingly:

  magrathea.hanzalova.internal  10.6.0.194  (postgres primary)
  caveman.hanzalova.internal    10.6.0.186  (minio, gitea)
  nikola.hanzalova.internal     10.6.0.173
  frootmig.hanzalova.internal   10.6.0.131

The old *.kosherinata.internal names remain as transitional DNS aliases
and will be removed once deploys use the new names.
