New Portainer stack: jellyfin, jellystat + postgres, wizarr and
jellyplex-watched. Bulk data (metadata, trickplay, cache, transcodes)
binds to /storage1; only SQLite config lands on the root disk.
Trickplay gets an explicit sub-bind because 10.11 moved it to
/config/data/trickplay, which is not relocatable from the UI. Transcodes
are disk-backed rather than tmpfs because jellyfin#16608 orphans segments
on the Remux/DirectStream jobs that are routine on this server.
