Earn vault totals history

Returns aggregator-level Earn vault totals history. This endpoint uses Earn semantics and intentionally omits EVK-only borrowed, cash, and utilization fields. Fresh Earn snapshots serve current totals, APY, and share price without Ponder or RPC work; missing or stale snapshots retain the indexed/live fallback. Historical USD values use bucket-aligned asset prices when available and remain null when pricing is unavailable. The effective end is to or the current time. When from is omitted, the effective window is 7 days for 1h and 30 days for 1d. Ranges count both endpoint buckets and support at most 744 hourly buckets or 732 daily buckets. Each point includes a nullable sharePriceQuote with exact assets per whole share and block provenance. Coverage evaluates assetsPerShare separately from the raw sharePrice ratio and APY. Quote unavailability does not suppress other available metrics or synthesize historical quotes.
