Update project timeline and subitem dates on change

Your Payments edits leave subitem dates out of sync, confusing contractors and delaying invoices. Keep timelines and subitem dates aligned so crews and billing staff have correct schedules same day.

Overview

When Payments edits drift across subitems, crews arrive with wrong dates and billing gets delayed; this flow keeps subitem dates and the parent timeline consistent so crews and billing staff have accurate schedules. Implementing it delivers updated timelines within minutes, reducing manual fixes and same-day confusion.
