x1458 client—Indicate that probe hyb QC will only be recorded on slots that have had the prob hyb operation

[khelwood]

I've added a graphql query to find out which slots in a particular labware this applies to. Client needs to fetch this info and update the UI to indicate which slots are involved in the page for probe hyb QC.

"""Gets info about which slots have been used in probe hybridisation."""
