[NorkzYT]

https://github.com/user-attachments/assets/41a659c9-6def-4492-be8e-5910eb148d6f

This PR enforces login‑first access (#8716) by disabling or enabling the guest demo workspace via Admin Server Client Page and redirecting unauthenticated users straight to /sign‑in.

Summary by CodeRabbit

• New Features
  • Added a configuration option to control whether guests can access the demo workspace.
  • Server and client interfaces, as well as GraphQL queries and schemas, now support and expose the guest demo workspace setting.
  • User navigation after sign-out has been updated to redirect appropriately based on the guest demo workspace setting.
  • Unauthenticated users are redirected to sign-in if guest demo workspaces are disabled.

Walkthrough

A new configuration flag, allowGuestDemoWorkspace, was introduced to control whether guest users can create demo workspaces. This flag is integrated across backend and frontend configuration, GraphQL schema, queries, and UI logic, with corresponding updates to access control, navigation, and tests to reflect the flag's value.

Poem

A toggle for guests, now added with care,
Controls if demo workspaces appear anywhere.
If true, guests may roam and try out the site,
If false, they’re guided to sign-in’s bright light.
Code and config in harmony sing—
Flexibility’s here, let the rabbits spring! 🐇✨

@NorkzYT the ci checks pass. plz sign the CLA so we can merge your code right now

[NorkzYT]

Done.

[NorkzYT]

The commit I made now ensures backward compatibility with older servers.

[NorkzYT]

Fixing the typecheck.

[fengmk2]

@NorkzYT There is still a bug. I set the allowGuestDemoWorkspace to false on https://affine.fail, but when I first open https://affine.fail in an incognito window, it still creates a demo workspace. Only when I open https://affine.fail a second time does it redirect to the login page. There seems to be a state issue here.
