az login and az account set fail with HTML-encoded characters and subscription not found

### Describe the bug

When using Azure CLI on macOS with zsh, commands like `az account set` fail due to HTML-encoded characters like `<` and `>` being interpreted literally.

Also, even after successful login and selecting the correct subscription, Terraform fails to detect the subscription ID, and Azure CLI shows:

### Related command

az login
az account list
az account set --subscription ""

### Errors

zsh: no such file or directory: SUBSCRIPTION_ID
The subscription of '' doesn't exist in cloud 'AzureCloud'.
zsh: missing end of string

### Issue script & Debug output

az login --debug
az account set --subscription "" --debug

### Expected behavior

Azure CLI should correctly parse and set the subscription ID. HTML-encoded characters should not appear in the terminal. Terraform should be able to detect the subscription ID from the Azure CLI session.

### Environment Summary

az --version

### Additional context

Using macOS with zsh. Commands copied from web sources seem to include HTML-encoded characters like `<` instead of `<`, which causes parsing issues.
