Wrong password reset URL for Einstein@home #7087

Describe the bug

The Einstein@home "lost password" URL appears to have changed and needs to be updated.
[I am not entirely sure this is the right place for this, but it is accessed through the Manager.]

Steps to reproduce

1. Try to add the Einstein@home project as an existing user
2. Realise you forgot your password
3. Click the "Forgot your password" link in the dialog
4. Get directed to the 404 page https://einsteinathome.org/get_passwd.php

Expected behavior

I should have been directed to https://einsteinathome.org/user/password

System information

Windows 11 25H2
