When customers pay for ADP quotations through the portal, the system was charging the full order amount (ADP + client portions combined). Now correctly charges only the client portion (25% for REG clients). Changes: - Override _get_prepayment_required_amount() to return client portion - Override _has_to_be_paid() to skip payment for 100% ADP-funded orders - Add portal controller to cap payment amount at client portion - Add portal template showing ADP funding breakdown to customer
