[BUG] list methods failed to get all properties of Vault

### API Spec link

https://github.com/Azure/azure-rest-api-specs/blob/main/specification/recoveryservices/resource-manager/Microsoft.RecoveryServices/RecoveryServices/Vault.tsp#L204

### API Spec version

2025-08-01

### Describe the bug

When get Vault by calling the `get` operation, we are able to get all properties from the model, yet when do it by calling `list_by_subscription_id` or `list_by_resource_group`, property `securitySettings` and `redundancySettings` are missing.

### Expected behavior

`securitySettings` and `redundancySettings` should be reachable from VaultList.

### Actual behavior

We can not find these properties in the response, although they are available when call the `get` method to get them.

### Reproduction Steps

calling method https://learn.microsoft.com/en-us/rest/api/recoveryservices/vaults/list-by-subscription-id?view=rest-recoveryservices-2025-08-01&tabs=HTTP

### Environment

_No response_

Start with the Vault.tsp API specification at line 204 and compare the get operation with list_by_subscription_id and list_by_resource_group. Verify how VaultList is defined and whether its responses expose securitySettings and redundancySettings; done means both properties are reachable from each list response as they are from get.
