Delete listing

Delete a seller-owned listing by deactivating it.

Deletion in this API is soft-delete behavior for marketplace safety:

• The listing is not physically removed immediately.
• The API sets listing quantity to 0, which removes it from active selling flow and indexing pipelines.

Rules and constraints:

• Listing must belong to the authenticated seller.
• Listing must currently be active (quantity > 0).
• Deletion is blocked when active holds exist and returns 423.

Response:

• Returns 204 No Content when the listing is successfully scheduled for deletion.
• Returns 404 when the listing cannot be found for the authenticated seller.
