fix(app): support drop tip CTAs when two pipettes have tips attached

[mjhuff]

Overview

In 8.0, drop tip wiz now shows CTAs when a run is successful, and we determine tip attachment status solely from the history of tip attachment commands. Because of this, it's likely users will have protocols similar to the following:

left_pipette.pick_up_tip()   
[do something without dropping the tip explicitly in the protocol]
right_pipette.pick_up_tip()
[do something without dropping the tip explicitly in the protocol]
[end protocol]

In these situations, we want to prompt users to check tips on both pipettes.

This is simple in theory, but in practice, there are a lot of side-effects we have to consider: run status, whether the run is current, which app is controlling the robot, how to properly load the correct pipette...there's a lot of variables. Unfortunately, drop tip wizard in its current iteration is already overloaded and in need of a refactor. Following the control flow is difficult to say the least. If you're brave, #15947 offers some context behind the most recent systems created.

Test Plan and Hands on Testing

• Smoke tested all drop tip flows and interactions, ensuring correct behavior. I used this protocol.

Changelog

• New drop tip CTAs support dropping tips from two pipettes, if applicable.

Review requests

There is a lot we can do to clean this up, but this entire flow is getting a facelift for 8.1, so I think it's safe to focus on functionality for now.

Risk assessment

• lowish-med. I smoke tested this thoroughly.

is this leftover debugging?

a few comments but code changes look good to me
