Fix semester system: 2x yearly docs, 4x yearly payments with Q4 on Sep 15

Browse Source 
Document Submission (twice yearly):
- Q1 & Q2 documents: Due March 15 (Spring semester)
- Q3 & Q4 documents: Due September 15 (Fall semester)

Payment Schedule (quarterly):
- Q1 payments: Due March 15
- Q2 payments: Due June 15
- Q3 payments: Due September 15
- Q4 payments: Due September 15 (aligned with Fall semester docs)

This gives the desired Q4 payment due date of 15.09.2025 while maintaining
quarterly payment frequency and semester-based document submissions.
