fix(step-generation): correctly grab single well from well sets in ROW configuration

[ncdiehl11]

Overview

This PR fixes a bug in the getTargetTipsFromWellSets utility through which nested lists of wells passed to liquid handling functions are reduced to a flat list of target wells.

Closes RQA-5623

Test Plan and Hands on Testing

• import protocol attached to the ticket
• in step 8, navigate to final page of form (tip settings)
• select manual tip seletion, and select a valid set of tips
• save and verify no timeline error

Changelog

No transposition is needed for ROW configuration well sets; rather, we should just grab the first well of each set to target (example: input rows [[H1, H2, ..., H12], [G1, G2, ..., G12]] should return [H1, G1]
