## Summary by CodeRabbit

* **New Features**
* Added a new `LocalWorkspace` feature flag to server configuration,
enabling more flexible feature management.

* **Deprecations**
* The `allowGuestDemoWorkspace` flag is now deprecated and will be
removed in version 0.25.0. Please use the `features` array for feature
checks instead.

* **Bug Fixes**
* Updated UI and logic throughout the app to rely on the new
`LocalWorkspace` feature flag rather than the deprecated boolean flag.

* **Chores**
* Removed references to `allowGuestDemoWorkspace` from configuration,
queries, and type definitions for improved consistency.
