fix(accounting): guarantee_type dropdown offered values not in the live ENUM

نفس فئة الغلط بتاعة نوع القرض: القائمة كانت بتعرض initial/final/advance
بينما الـ ENUM الحقيقي في القاعدة tender/performance/advance_payment/
maintenance/customs/other — فأي اختيار غير maintenance كان يفشل الحفظ
بـ Data truncated for column 'guarantee_type'.
