fix: use {{entire_url()}} for all Menu url paths in index.ui and login.ui

- Menu items now use {{entire_url('/module')}} instead of hardcoded paths
- Iframe src also uses {{entire_url()}}
- Register button in login.ui uses {{entire_url('/rbac/user/register.ui')}}
- Removed unnecessary binds for Menu widget (Menu handles click internally)
