Add the SPA screens over the new detail/info/image endpoints:
- Detail pages at /app/media/{movies|shows|seasons|artists}/{id}. MediaBrowseScreen
cards for movies/shows/artists (and season/show drill-in cards) navigate to them.
Shows list seasons -> seasons list episodes -> artists list music videos, each via
the browse parentId drill-in, paged. Layout: fanart/poster, title/year/plot, chip
lists, cast row, movie path + FileNotFound/Unavailable warnings. A "Media Info"
dialog (streams + chapters) backs onto GET /api/media-items/{id}/info. Add-to-
collection/playlist deferred to #153/#155 (TODO left in code).
- Image folder browser at /app/media/images/browser: lazy expandable tree, per-folder
image/subfolder counts + duration, edit dialog (PUT set/clear), and a per-folder
search link (library_folder_id:{id}). Reachable via a "Folder Browser" button on the
Images browse view.
New /app/media sub-paths are owned by a MediaRouteScreen wrapper that tracks pathname
locally + listens for popstate (App-level routing returns the same 'media' route object
for base and sub-paths). Client modules web/src/api/mediaDetail.ts + imageFolders.ts,
typed via the generated v1.d.ts.
