Overview

This bug is interesting. Basically the logic for the different change tip options needed to be refined because there were states when the selection was not disabled but you couldn't successfully set it. Looking at the logic, we needed to account for the well ratio being set. Since the introduction of the trash bin/waste chute, those entities are not labware and are addressable areas. So they don't have wells to select, therefore the certain option such as perDest and perSource should be disabled

Test Plan

Create a flex or ot-2 protocol with a single channel and an 8 channel. Add a 1 well reservoir and a 12 well reservoir.

Create a transfer step where you aspirate from the 1 well reservoir and dispense into the trash bin. See that the change tip dropdown's per source and per dest are disabled. Now change the dispense location to 1 well/column in the 12 well reservoir. See that the per source is enabled and selectable and the per dest is still disabled. Then change the dispense location to 2 wells/columns in the 12 well reservoir. See that the per dest is enabled but the per source is disabled.

Repeat those steps with the other pipette.

Note: only the move liquid form needed to be updated since the mix form does not allow you to mix into a trash bin or waste chute.
