Add Anki route and fix Jellyfin cache disk exhaustion

- Add adyrem.duckdns.org/Anki → claude-code VM:4002 via Traefik
- Add anki.homelab DNS entry to Pi-hole
- Mount Jellyfin transcode cache to /media/transcodes (HDD) instead of
  anonymous Docker volume on root disk; prevents root disk from filling up
