Add *arr media stack + Gitea to jupiter

- sabnzbd, prowlarr, sonarr, radarr, clonarr, seerr, cinephage, mediamanager
  services, wired into jupiter with LAN Caddy vhosts.
- Gitea: migrated the old ZimaOS docker instance's data (sqlite db, 4 repos,
  no LFS objects) into the NixOS module's default stateDir layout. HTTP via
  Caddy; git SSH on its own built-in server at :2222 (not :222 - the unpriv
  gitea user can't bind <1024).
- mediamanager-nix flake input for the mediamanager service.
