npeter83 6db7014b08 feat(welcome): landing lightbox, prod-served screenshots & session-end UX
- Serve real files at the SPA root (e.g. /welcome/*.png, favicon) from the built app — the
  landing screenshots were only ever shown by the Vite dev server, never in production.
- Add the Channel-manager screenshot; the two secondary previews are smaller thumbnails that
  open in a custom full-size lightbox (fit-to-viewport, Esc/backdrop/✕ to close).
- Drop a suspended/deleted user to the login page on the next 401 (and poll the session only
  while signed in, so the public login page no longer flickers); 'suspended' and 'account
  deleted' confirmation banners; strip redirect query params for a clean address bar.
