az network vnet create intermittently fails with Python 3.14 _ModuleLock deadlock while importing requests.structures

### Describe the bug

On a GitHub-hosted Ubuntu 24.04 runner, `az network vnet create` intermittently fails because Python detects a module-lock deadlock while importing `requests.structures`. The failure occurs with Azure CLI 2.89.1 and its bundled Python 3.14.6. It makes our AKS CI workflow flaky: rerunning the same workflow may succeed.

### Related command

```
az network vnet create \
--resource-group aks-1 \
--location westus \
--name aks-vnet \
--address-prefixes 192.168.8.0/22 fd00::/48
```

### Errors

```
ERROR: The command failed with an unexpected error. Here is the traceback:

### Expected behavior

`az network vnet create` should create the virtual network successfully without encountering a Python module import deadlock.
