refactor: add more selectors for Zuora panel

What

Add env, and type selectors for the Zuora panel.

Why

At the moment we are only using environment=gprd and the same metric name can be used by some other service so using type is necessary to make sure the panel doesn't break in the future.

Add env for consistency as well.
