jellyfin sidecar: server registry, video façade and byte pass-through

officer-jellyfin owns the whole Jellyfin contract: the instance URL, the access
token, the Jellyfin user it belongs to and the DeviceId its sessions are keyed
by. The platform side is a 17-line proxy holding no credentials.

Servers are a registry, not a single row — this machine runs four instances and
the owner switches between them. The password is never stored: it is traded once
for an access token through AuthenticateByName, and only that token is persisted,
encrypted.

Two doors. /_officer/* is a hand-written JSON façade for the things the browser
should not have to know — the user id in the path, the Fields lists that decide
whether a grid has posters, the PlaybackInfo negotiation. /_jf/* is a GET-only,
allow-listed byte pass-through for images, video, HLS and subtitles; it keeps
Jellyfin's own paths because a master playlist references its segments
relatively, so any renaming would mean rewriting m3u8 bodies.

TranscodingUrl arrives with api_key=<access token> in its query string and would
otherwise be handed straight to a video element. It is stripped before anything
is returned; the pass-through re-adds the credential as a header.

Video only — Officer's own player owns audio, so music collections are filtered
out of the library list.

// The two halves of the Jellyfin surface Officer exposes.
//
// `/_officer/*` — a small hand-written façade. Every route here exists because the raw Jellyfin call needs
// something the browser should not have to know: the user id in the path, a Fields list that decides whether
// a grid has posters, or a PlaybackInfo negotiation. It is JSON in, JSON out.
//
// `/_jf/*` — a transparent, authenticated, GET-only pass-through for BYTES: images, video, HLS playlists and
// segments, subtitles. It exists because HLS cannot be faked. A master playlist references its variant
// playlists and every segment RELATIVELY, so the URLs a browser derives from it must resolve back onto the
// same prefix; any façade that renamed those paths would have to rewrite the playlists on the way out, and
// rewriting m3u8 bodies to keep a prettier URL scheme is a trade nobody should take.
//
// The pass-through is deny-by-default over a prefix allow-list. Jellyfin's API is the whole server —
// `/System/*`, `/ScheduledTasks/*`, `/Plugins/*`, user administration, the setup wizard — and the token this
// sidecar holds belongs to a real account, so an "everything under /_jf" proxy would put library scanning and
// user creation one URL away from the browser.
//
// One thing here is a security fix rather than plumbing: `TranscodingUrl` comes back from Jellyfin with
// `api_key=<the access token>` embedded in its query string. That URL is handed to the video element, so it
// would put the token in the DOM, in history and in any log that records URLs. It is stripped in
// `sanitizeUpstreamPath` before anything is returned, and the pass-through re-adds the credential as a header

//
// The server is CONFIGURED BY THE OWNER FROM THE UI and stored encrypted in `jellyfin_servers` (see
// databases/officer_db/src/queries/jellyfin.ts). Nothing in this file reads process.env — Bun auto-loads
// `.env` into every process started in the platform directory, so a token there would also be sitting in
// `officer`'s own environment: a credential held by the one process that has no code to use it.
//
// Three things about Jellyfin's API are load-bearing:
//
// 1. Auth is ONE header — `Authorization: MediaBrowser Token="…", Client=…, Device=…, DeviceId=…,
// Version=…`. The older `X-Emby-Token` still works in 10.11 but carries no client identity, and
// playback reporting correlates sessions by DeviceId, so the full header is what we send.
// 2. The DeviceId must be STABLE per server. A fresh one per request fills Jellyfin's dashboard with
// hundreds of "devices" and detaches each progress report from the session that started playback.
// 3. Almost every per-user route needs the user id in the PATH (`/Users/{id}/Views`), and it is not
// derivable from the token without a round trip — which is why it is pinned on the row at sign-in.
