Entry Screen

I want my app to have an entry screen as follows

<img width="1624" height="388" alt="Image" src="https://github.com/user-attachments/assets/7f6c1382-97ce-42fe-a5dd-a2c637815222" />

This will be shown for unauthenticated users.

There will be a sign in button on the screen that will redirect to the current dashboard but must go through am oidc login flow to authenticate the user
