fix: missing string in array of union type in OrderResponse type

[stoyanov-kaloyan]

Discovered this issue while validating against the OrderResponse type.

When submitting an array of three orders with the normalTpsl grouping [market order, tp, sl] the Hyperliquid API returns a response of this format

{
    "status": "ok",
    "response": {
        "type": "order",
        "data": {
            "statuses": [
                {
                    "filled": {
                        "totalSz": "0.00022",
                        "avgPx": "87102.0",
                        "oid": 272900270573
                    }
                },
                "waitingForTrigger",
                "waitingForTrigger"
            ]
        }
    }
}

Notice that sometimes a status can be just a string

Fix: Adding a v.string() in the union type of the statuses array fixes this issue
