Support `instanceIdPrefix` filtering in instance queries (getStatusBy)

The Durable Task extension HTTP API supports filtering instance queries by an instance ID prefix. For example:
`GET /runtime/webhooks/durabletask/instances/?instanceIdPrefix=xyz1234`

Currently, the .NET and Python SDK expose this capability, but the JavaScript/Node.js SDK does not expose a parameter for it when querying statuses (e.g., via `getStatusBy`).

Additional context:
This feature was recently added to the Python SDK to achieve parity with .NET:
* Python PR: [Azure/azure-functions-durable-python#604](https://github.com/Azure/azure-functions-durable-python/pull/604)
* Python Issue: [Azure/azure-functions-durable-python#601](https://github.com/Azure/azure-functions-durable-python/issues/601)
* Similar issue(Python): [Azure/azure-functions-durable-python#467](https://github.com/Azure/azure-functions-durable-python/issues/467)

Start by reading the JavaScript/Node.js SDK's `getStatusBy` query API and compare its available parameters with the `instanceIdPrefix` filtering described in the issue and the linked Python implementation reference. Identify the query construction and its tests, then verify that callers can pass a prefix and that the resulting query filters instance IDs as requested.
