detect #rebase payments made on Nomad List account during November before I had a Rebase profile on Stripe and move them into Rebase in payments.db for /open pages
add future timeline based on expected times #rebase (later we can adjust this to actual estimated based on previous applicants times logged for milestones)
add dynamic Stripe Checkout (instead of manual payment links) to #rebase with callback that sets applicant as paid db (making Rebase fully automated now instead of copy pasting emails from Stripe dashboard into db)
