🐛 Bug Report

Site preview domains are unreachable on self-hosted 2.2.0. The API redirects preview
requests to the Console route /auth/preview, but the bundled Console image
(appwrite/new:1.1.96-self-hosted) does not implement that route, so the browser
lands on the Console's 404 page and preview authorization can never complete.

Steps to reproduce

1. Self-hosted 2.2.0 via the official docker-compose.yml, with _APP_DOMAIN_SITES configured.
2. Deploy a Site and open its deployment-specific preview domain:
   https://<deploymentId>.sites.example.com/
3. Follow the redirect.

Expected

The Console serves a preview-authorization screen, sets the preview cookie, and
returns to the deployment URL.

Actual

GET https://<deploymentId>.sites.example.com/
  → 301  https://console.example.com/auth/preview?projectId=<projectId>&origin=…&path=%2F

GET https://console.example.com/auth/preview?…
  → 404  "404 — Page not found" (Console error page, title "Appwrite Console")

The Site's own active domain works fine — that path is not a preview domain, so
$isPreview is false and the preview check never runs.

Evidence

Measured against a 2.2.0 instance (GET /v1/health/version → {"version":"2.2.0"}):

The route is absent from the shipped Console bundle. In
/assets/index-<hash>.js (~6.4 MB) the string auth/preview occurs 0 times,
and no preview-related route is registered at all (previewAuth, previewToken,
disablePreviewAuth: 0 occurrences each).

The redirect is built in
app/controllers/general.php (2.2.0):

->redirect($url . (System::getEnv('_APP_CONSOLE_URL_SCHEME', 'legacy') !== 'root'
    ? '/console/auth/preview?'
    : '/auth/preview?')
    . \http_build_query([...]));

Both values of _APP_CONSOLE_URL_SCHEME end in the same 404: with root the API
targets /auth/preview directly; with legacy it targets /console/auth/preview,
which the Console redirects (302) to /auth/preview. So the setting is not a workaround.

Environment

• Appwrite 2.2.0, self-hosted, Docker Compose
• Console image appwrite/new:1.1.96-self-hosted (as shipped in the 2.2.0 compose file)
• The appwrite-console service is unmodified from the upstream 2.2.0 docker-compose.yml
• Traefik in front, reverse proxy upstream of that
