Remove user from business

DELETE/api/v1/businesses/users/{user_id}

Remove a user from a specific business.

IMPORTANT: This endpoint removes the user-business association ONLY. The user record itself remains in the database and can still be associated with other businesses.

The business's last owner cannot be removed (400) — transfer ownership first so the business is never left without an owner.

To completely delete a user from the system, use DELETE /users/{user_id} instead.
