dtourolle 88e15e3e12 merge: Android runtime security (B1, B3)
Correct the POST_NOTIFICATIONS mechanism: the lockscreen notification is exempt
because of the MediaSession token, not because it belongs to a foreground
service — FGS notifications are explicitly NOT exempt. So no permission prompt
and no checkSelfPermission gate; instead both notification builders bind the
token once and log loudly if it is ever null, turning a silent failure into a
logcat line. Stop the webview undoing the network security config:
mixedContentMode COMPATIBILITY, allowFileAccess/allowContentAccess false.

Conflict resolution: this branch's DR-198 collided with the Tauri branch's, so
it was renumbered DR-200 (3 TRACES in JellyTauPlaybackService.kt and the UR-006
matrix row updated). DR-199 was uncontested. Pinned counts summed to DR 191 /
total 334; UR-071 takes both DR-198 and DR-199.

dtourolle 2d21f092d5 fix(android): stop the webview undoing the network security config
MainActivity set mixedContentMode = MIXED_CONTENT_ALWAYS_ALLOW together with
allowFileAccess/allowContentAccess = true, which is a blanket cleartext opt-in
reached by hand — the exact thing network_security_config.xml exists to prevent
and its own comment warns against. Nothing needed any of the three:

- file:// is never loaded. Cached thumbnails go through convertFileSrc, which
  on Android resolves to http://asset.localhost/... and is answered by wry's
  request interceptor rather than the filesystem; downloaded media goes over the
  loopback HTTP server (DR-137), which exists precisely because the asset/file
  route cannot stream a large file.
- content:// is never loaded. The manifest's FileProvider is for outbound share
  intents, not webview navigation.
- Mixed content never arises. Tauri serves the UI from http://tauri.localhost
  (use_https_scheme defaults false and is not set), and both 127.0.0.1 and
  asset.localhost are loopback/.localhost origins Chromium treats as potentially
  trustworthy. A plain-HTTP remote server would be mixed content, but the network
  security config already rejects it first — so ALWAYS_ALLOW bought nothing.

COMPATIBILITY_MODE rather than NEVER_ALLOW is a deliberate hedge: the platform
default at targetSdk 21+ is NEVER_ALLOW, so this is still one step looser, and it
keeps passive content working if the analysis missed a path. The two files now
cross-reference each other so the pair cannot drift apart again.

Also records why POST_NOTIFICATIONS is declared but never requested. An audit
read the missing runtime request as a threat to the lockscreen controls; it is
not. A foreground-service notification is explicitly NOT exempt, but a
media-session one is, and the platform predicate (Notification.isMediaNotification)
requires MediaStyle AND a non-null session token. Confirmed on device: appops
POST_NOTIFICATION: ignore with the transport notification live. So no permission
prompt is added and startForeground stays ungated — a guard there would trade a
cosmetic problem for the "did not then call Service.startForeground()" kill.
What is added is the guard matching the real precondition: both builders bind the
token once and log an error if it is ever null, since SystemUI's media carousel
is gated on the same predicate and a token-less notification loses the lockscreen
controls entirely, silently.

TRACES: UR-006, UR-071 | DR-198, DR-199

dtourolle 38dd1129e5 feat(security): set a restrictive CSP and scope the asset protocol to thumbnails
`app.security.csp` was `null`, so the webview ran with no Content-Security-Policy
at all: any script that reached the web layer would have inherited the whole IPC
surface. There is no known injection path today (one app-owned `{@html}`, no
`innerHTML`/`eval`), so this is defence in depth rather than a fix for an open
hole.

`script-src 'self'` is the restrictive half — Tauri nonces SvelteKit's inline
bootstrap script at build time, so no `'unsafe-inline'` is needed — together with
`object-src`/`frame-src 'none'` and `base-uri 'self'`. `img-src`/`media-src`/
`connect-src` cannot be restrictive: the Jellyfin origin is typed in by the user
at run time and is routinely plain http on a LAN, so they allow `http:`/`https:`.
That is a wide grant for data, but it still bars `file:`/`filesystem:` and does
not touch script execution. A run-time policy naming the server exactly was
rejected: Tauri derives the header from immutable config when it serves the HTML,
so it would mean rebuilding config and reloading the webview on every server
change. `style-src` keeps `'unsafe-inline'` because Svelte compiles `style="…"`
attributes into markup; `worker-src`/`media-src` keep `blob:` for hls.js's
demuxer worker and its MSE object URL; `ipc:`/`http://ipc.localhost` keeps
`invoke` working. `devCsp` mirrors it with the eval/inline/websocket allowances
Vite's dev server needs.

The asset-protocol scope narrows from `$APPDATA/**` — the storage root holding
the SQLite database and the encrypted-token fallback file — to
`$APPDATA/thumbnails/**`. Since DR-137 moved downloaded media to the loopback
media server, `imageCache` is the only `convertFileSrc` caller left.

Needs manual verification on both platforms: thumbnails, online HLS video and
offline downloaded video cannot be exercised headlessly.
