P6: Add Kiwix and Transmission k8s manifests

- Transmission: General-purpose torrent daemon with web UI at torrent.tail8d86e.ts.net
- Kiwix: ZIM archive server at kiwix.tail8d86e.ts.net
- Shared NFS storage from sifaka:/volume1/torrents (no CSI driver needed)
- Declarative ZIM management via ConfigMap synced to transmission
- ZIM watcher CronJob to auto-restart kiwix when new ZIMs appear
