Overview

Delete a vendor. The vendor's user account is not permanently removed — it is converted back to a regular customer.

Example: Remove a vendor who is no longer providing services.

Important Behaviors

• Cannot delete with bills: A vendor with existing bills cannot be deleted. Returns 400.
• Converts to customer: The vendor record is deleted, but the underlying user account is preserved and converted to a customer (type changes from vendor to customer).
• Event fired: vendor.deleted event is dispatched after successful deletion.
