Update monthly donation records from sheet to database

Donation rows land in a sheet unreconciled, leaving member giving totals stale and staff unable to confirm payments. Keep donor balances and monthly payment methods accurate so reporting and outreach happen same day.

Overview

Stop manual donation reconciliation and give finance and program coordinators a single reliable donor ledger. This flow writes new gift rows into the donor database and updates monthly totals within minutes, enabling same-day reconciliation and outreach.
