Feature Request: Auto-redirect to SSO when Regular Login is disabled

[JanFPV]

Hi!

First of all - the app is wonderful.

I have configured LinkAce with a single SSO provider (Authentik) and set REGULAR_LOGIN_DISABLED=true in my .env file.

Currently, when accessing the login page, I am presented with a screen containing a single button ("Login with Authentik"). This requires an unnecessary extra click every time I want to access the app.

It would be great to have a new parameter (such as SSO_AUTO_REDIRECT=true) or logic to automatically redirect the user to the SSO provider flow, skipping this intermediate screen entirely when regular login is disabled.

Thanks for the great work!
