Update ExpandRecurringBillingEventsAction to use the beam pipeline (#1907)

Due to the way the beam pipeline is designed, it will expand an recurring billing event when its event time is in scope for expansion, instead of billing time. This means that the one time will be generated 45 days earlier. This would negate the need to check if the expansion is finished when generating monthly invoices. We will need to backfill the past 45 days of onetimes before the new code is deployed. As an illustration, with the old code, a cursor time of 2023-01-17 means that all auto-renewals whose billing time is before 2023-01-17 were created, which corresponds to an effective cursor time of 2022-12-03 (45 days before 2023-01-17) for event time. This cursor will need to be brought to 2023-01-17 to ensure that there is no gap in generated event times when switching to use the new code.
