Make certain JGI columns always read-only in DataHarmonizer

Re: microbiomedata/issues#412 (will close once it has been tested on dev)

These changes make a set of JGI-related columns read-only in DataHarmonizer. This does not prevent the columns from being populated by importing an XLSX file. This is a feature, not a bug.

To test:

• Go to any submission with a JGI MG and/or JGI MT tab
• Enter data in the first tab to ensure that some rows will display in the JGI tab(s)
• On the JGI tab(s) ensure that the indicated columns cannot be edited

LGTM!

@pkalita-lbl Looks great!!
I think when we have the API, we will have to look into not including these columns in the sheet download. Cuz if I edit it in excel, and then import it does change the values. But I think that's a different issue. I think that is part of the API development.

I like that the cursor turns into a 🚫 when hovering over those columns.
