Session Expired page redirects to app.base44.com instead of custom domain

When a user's login session expires on a custom domain app, the "Try Logging In Again" button on the session expired page redirects to app.base44.com instead of back to the custom domain login page.

Steps to reproduce:

1. Log into an app hosted on a custom domain (e.g. logatrade.com)

2. Let the session expire or trigger a session timeout

3. Click "Try Logging In Again" on the error page

4. It redirects to app.base44.com instead of logatrade.com/login

Expected behaviour: The button should redirect back to the app's custom domain login page.

Actual behaviour: Redirects to app.base44.com which is confusing and unprofessional for end users who have no idea what Base44 is.

This is a significant issue for any Builder+ plan user running a production app on a custom domain. Please fix the redirect logic to respect the custom domain.
