Description:

An admin can delete their own account from the Admin > Users panel. There is no restriction preventing self-deletion from this interface, which immediately breaks the active session and can leave the workspace without an admin if no other admin exists.

Steps to reproduce:

1. Log in as an admin
2. Go to Admin > Users
3. Find your own user in the list
4. Click the three-dot actions menu
5. Click Delete — no restriction, account is deleted immediately

Expected behavior:

The Delete option should not be available for the currently logged-in admin's own account in the Users panel.

Actual behavior:

Delete option is shown and functional. Clicking it deletes the admin's own account, immediately breaking the session. Browser console shows:
You must be logged in to do this.
