Recent order history for a wallet on Hyperliquid

HL Info `historicalOrders` — recent placed orders and their final status (filled / canceled / triggered / rejected), in `native`. HL returns only the most recent batch (~2000), so this is NEAR-TERM history, not lifetime. Public — `?user=` lowercased, wallet need not belong to the caller org. TTL-cached to bound HL rate-limit cost. NO `?dex=` param: unlike `open-orders`, HL's `historicalOrders` does NOT scope by dex — the result already spans EVERY dex (main perp + HIP-3 orders mixed), so a wallet's HIP-3 order history is already included here. NOTE: this is the ORDER lifecycle (includes unfilled/canceled); a forced liquidation is a system action NOT reliably represented here — to tell a manual close from an automatic liquidation use the fill's `liquidation` marker via `/v1/me/fills`.
