Get vault forward repayment schedule

Projected weekly repayment volume carried forward at each facility's trailing run-rate, bucketed on UTC-Monday calendar weeks — the same buckets the realized series uses. The first projected entry is the next Monday; entries remains realized-only for the in-progress week (paid rows only, never partial). The in-progress week is additionally carried by the top-level currentWeek object: realized receipts to date plus, per facility, a projected gap-to-pace remainder — a re-projection of numbers already public elsewhere in this response, not new information. There is no on-chain instalment schedule — every entry is an explicit projection (status: "projected"), not clamped to deadline (most borrowers roll over; deadline is a UI marker only). Only the single v2 vault is supported; other vaults 404.
