lilleman 1d198acc97 Canonical host via APP_URL: stop login dumping users on /error from a host mismatch
The from-scratch dev login was broken: open the banner's http://localhost:3000, sign
in as the seeded admin, and you landed on http://127.0.0.1:3000/error "Page not found".
Root cause: the banner/APP_URL said localhost but kratos.yml hard-coded 127.0.0.1, and a
host-scoped Kratos CSRF cookie can't cross localhost<->127.0.0.1, so the cross-host login
POST lost it; Kratos redirected to its error sink, which the app had no route for (404).

Make APP_URL the single source of truth for the public host:
- Canonical-host redirect (app.ts): when APP_URL is set, an off-host GET/HEAD visitor is
  308'd to it (path+query kept) before a flow starts, so the browser, the themed forms and
  the cross-origin Kratos POST share one cookie host. After /public/ so static/health
  checks stay host-agnostic; GET/HEAD only so a 308 never replays a cross-host POST.
- Opt-in (no NODE_ENV / no magic default): unset => no redirect, so a prod deploy that
  forgets APP_URL can't bounce real users to a stale default. The dev stack sets it.
- kratos.yml browser URLs default to localhost (match APP_URL's dev value) and derive from
  ${APP_URL} via compose.override.yml; SERVE_PUBLIC_BASE_URL keeps the dev Ory port.
- Real /error page (views/error.ejs) replaces the catch-all 404 for genuine flow errors.

Tests-first: config (opt-in/validated), app (308 on mismatch, no-redirect on match, static
host-agnostic, POST untouched, /error page), updated kratos.test host pins. New devstack
regression (e2e/devstack-login.spec + compose.e2e-devstack.yml) drives the plain
docker-compose-up topology on the host network: login from localhost works and 127.0.0.1 is
canonicalised; wired into scripts/ci.sh. typecheck + 360 units + full ci.sh (visual 10 ·
auth 1 · oauth 2 · full 7 · devstack 2) green.

# Full-stack OAuth2 E2E — the §6 login-challenge handler. Another app logs in *through* us:
# Hydra starts an authorization flow and hands the browser to web's /oauth2/login; web resolves
# it via the Kratos session and accepts. Runs against the real stack (Postgres + Kratos + Keto +
# Hydra + bootstrap + web). The runner drives the flow over HTTP (fetch, manual cookies), so it
# reaches the Ory services by their compose-network names.
