Probe whether a serial is valid for a return

Non-destructive check: verifies that the scanned serial number was on the original shipment for the given order. Returns a verdict object without throwing. Useful for inline scanner UI feedback before submitting a receive.

Response shapes:

• valid: true — serial is sold, linked to the original order, and not yet returned.
• valid: false — serial exists but fails one of: wrong order, not sold, already returned.
• valid: null — no original_order_id supplied; cannot validate.

This endpoint honors the entity’s settings.returns.serial_validation_mode in the sense that its verdict is for informational use; the actual gate is enforced by POST /v1/returns/:id/receive and POST /v1/returns/:id/disposition when serial_validation_mode is hard. Requires the serials:read scope.
