[Bug] Bug: purge_instance_history_by has incorrect parameter handling and time filter behavior

### Expected Behavior

The created_time_from parameter should be optional, and the time filters should be combined with an intersection (AND) to allow precise time intervals.

### Actual Behavior

Observe that the API returns a 400 Bad Request error.

### Steps to Reproduce
Use the following code to call purge_instance_history_by

```shell
await client.purge_instance_history_by(
created_time_to=datetime.now(timezone.utc) - timedelta(days=1),
runtime_status=[
df.OrchestrationRuntimeStatus.Completed,
df.OrchestrationRuntimeStatus.Failed,
df.OrchestrationRuntimeStatus.Terminated,
],
)
```
Observe that the API returns a 400 Bad Request error.

### requirements.txt file

```shell
azure-functions-durable==1.2.10
```

### **Description:**

When using the _purge_instance_history_by_ method in the _DurableOrchestrationClient_ I encountered the following issues:

1. **Missing Mandatory Parameter:**

The created_time_from parameter is treated as optional in the SDK, but it is actually mandatory in the underlying API. If created_time_from is not
provided, the API returns a 400 Bad Request error.

2. **Time Filter Behavior:**

The time filters (created_time_from and created_time_to) are combined with a union (OR) instead of an intersection (AND). This makes it impossible
to define precise time intervals for purging.

Start at purge_instance_history_by on DurableOrchestrationClient and review the behavior described in the issue alongside the azure-functions-durable==1.2.10 requirement. Use the provided call to verify that omitting created_time_from no longer produces a 400 response and that created_time_from and created_time_to define an intersecting interval.
