studio /studio: serve the rich home (gallery remove/edit/+ refs), not the minimal SPA

The web/dist chat SPA shadowed studio_home.html at /studio, dropping the
per-image affordances: delx (remove → POST /v1/library/status deleted),
the Fix dialog (type-and-edit → /v1/library/fix), and the + reference tray
(→ /upload/image → /v1/library/compose, up to 5 refs). Serve the rich home
explicitly; drop the dead /studio/assets route + the node web-build stage.
web/login.html still ships (server.py serves /login). v0.17.4
