Fix e621 images and the setup screen in the desktop shell

e621's CDN answers cross-site image loads that carry no Referer with a 403 (Chromium sends none from a custom-scheme page, then blocks the response as ORB), so images never appeared in the desktop app. The main process now attaches an e621 referrer to requests for its hosts. The shell also answers /api, /admin, /static and /health with a 404 JSON instead of the SPA fallback — that fallback made the setup screen's empty-URL connection test report "Connected" against the shell itself. The setup screen is now desktop-aware (no same-origin option, no "Use this server", clearer copy), and the smoke test runs against a throwaway profile and covers both regressions.
