feat(streaming): add jellyfin stack

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.

+# streaming stack — Jellyfin and its satellites.
+#
+# Storage split is deliberate: SQLite config on the root SSD, all bulk data
+# (metadata, trickplay, cache, transcodes) on /storage1. The root disk is only
+# 194G and has filled twice; nothing here may grow unbounded on it.
+#
+# Trickplay gets an explicit sub-bind because Jellyfin 10.11 moved it to
+# /config/data/trickplay and it is NOT relocatable from the UI.
+#
+# Transcodes are disk-backed, not tmpfs: jellyfin#16608 means Remux and
+# DirectStream jobs finish before the segment cleaner's first check, orphaning
+# segments. Plex already writes transcodes to virtiofs at a 48% transcode rate.
+#
+# Env convention: every service gets stack.env via env_file; var names there are
+# exactly what the containers read. No ${VAR} interpolation, no Portainer UI
+# env vars.
