feat(core): remove empty workspace (#13317)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

* **New Features**
* Added the ability to remove an empty workspace directly from the
workspace card when you are the owner.
* Workspace cards now display a "Remove" button for eligible workspaces.
* **Improvements**
* Workspace information now indicates if a workspace is empty, improving
clarity for users.
* **Bug Fixes**
* Enhanced accuracy in displaying workspace status by updating how
workspace profile data is handled.
