BREAKING CHANGE: Payment due dates now follow advance payment schedule: - Q1 payments: Due December 15 of previous year - Q2 payments: Due March 15 of same year - Q3 payments: Due June 15 of same year - Q4 payments: Due September 15 of same year Changes: - Updated create_quarterly_support_payment() to use advance schedule - Enhanced diagnostic commands to check advance payment dates - Added fix_advance_payment_dates command for comprehensive fixes - Updated fix_q4_payment_dates to correct Q4 from 31.12 to 15.09 This aligns with semester-based document submissions while maintaining the advance payment system where payments are made before each quarter.
