fix(app): Labware List Item responsiveness and stacking order

[smb2268]

Overview

This PR makes the labware list items responsive so the divider will be full width regardless of screen size. It also shows the "nested labware def" at the top of the labware list instead of in the middle

Test Plan and Hands on Testing

I tested this with multiple window widths and stacked labware configurations

Changelog

1. Remove width items from flex containers and fix the grid widths so that the list items will be responsive
2. Swap order of "nested labware def" - this is the top level labware that is "nested on" the adapter or module
