fix(protocol-designer): fix HighlightItems logic

[ncdiehl11]

Overview

This PR fixes implementation of HoveredItems. We first check if the hovered item is a labware, and if so, if it is an adapter. If it is an adapter with a module underneath, we highlight the module rather than the adapter. Otherwise, we highlight the labware/adapter itself.

Closes RQA-3951

Test Plan and Hands on Testing

• import this protocol and add a move step
• hover around the options for new location and verify that the highlight is correct

Changelog

• add logic for checking if highlighted item is an adapter on a module
• implement logic in returns for getLabwareItems and getModuleItems
