fix(apps-v5): get pipeline stage from pipeline_coupling

[775c679][1] removed the `pipeline`
object from the `info` object used to render the display in `apps:info`
to fix a deprecation warning. Unfortunately, it seems like this
introduced a regression as code that was referencing `info.pipeline` was
not updated to use `info.pipeline_coupling`, resulting in runtime
exceptions due to trying to access a property off of `undefined`.
