Add Jellyfin media stack (LXC 106, NVIDIA GTX 1060)

- New Ansible role: jellyfin — Docker + nvidia-container-toolkit setup,
  full *arr stack compose file (Jellyfin, qBittorrent, Radarr, Sonarr,
  Prowlarr, FlareSolverr, Jellyseerr), systemd service for auto-start
- New playbook: jellyfin.yml targeting media_servers group
- Inventory: add media LXC (10.10.1.50) to media_servers group
- Traefik: add internal .homelab routes for all 6 media services
- Pi-hole: add DNS records for all 6 media services → Traefik
- network-interfaces: DNAT port 6881 TCP+UDP → 10.10.1.50 for BitTorrent
- homelab-requirements.md: document full Jellyfin stack requirements
  including NVIDIA GTX 1060 passthrough approach and driver notes
- jellyfin-tools: original reference compose file from upstream

Infrastructure created on Proxmox:
- LXC 106 (media, Debian 12, privileged, nesting=1, 10.10.1.50/vmbr1)
- ZFS dataset hdd/media mounted at /media in LXC
- NVIDIA device passthrough entries in /etc/pve/lxc/106.conf

Note: NVIDIA driver 580.159.03 (.run) installed on Proxmox host — not
managed by apt (Debian only has 550.x which doesn't support kernel 7.x
or GTX 1060 Pascal as of this driver version).
