[v16] "Add Workspace" button missing; forcing URL creates broken "Ghost" record that cannot be deleted via UI

Information about bug

In ERPNext v16, the "Add Workspace" button is missing from the Workspace List view. Attempting to bypass this by manually navigating to /app/workspace/new-workspace-1 allows the form to render and save, but results in a corrupted "ghost" record.

1. The new workspace appears in the Workspace List.
2. Clicking on it results in a "Workspace [workspace name] does not exist".
3. Attempting to delete the record from the List view fails with a "Not Found" error, requiring CLI intervention to fix.

Steps to Reproduce:

1. Go to Workspace List (observe "Add Workspace" button is missing).
2. Manually append /app/workspace/new-workspace-1 to the browser URL to force the creation form.
3. Fill in the details (Title, Name, Module, For User) and click Save.
4. Go back to Workspace List; the new record is visible.
5. Click on the new workspace to open it -> Result: "Workspace [workspace name] does not exist".
6. Return to Workspace List, select the record, and attempt to Delete. -> Result: Error message "Not Found".

Expected Behavior:

1. The "Add Workspace" button should be visible in the List View.
2. Creating a workspace should generate a valid route and viewable page.
3. If a workspace is visible in the List, it should be deletable via the UI.

Actual Behavior:

• Creation: No UI button available.
• Routing: Saved workspace does not generate a valid route/view (404 error on load).
• Deletion: UI throws "Not Found" error when trying to delete the record, effectively locking it in the database until removed via bench console
