allow wgcna collections in correlation metadata app

[asizemore]

This PR includes changes that let folks see the wgcna data working in the correlations apps.

To run, use jbrestel plasmo backend.

02/02/24 - can select the collections for the correlation app. Found issue on the backend VEuPathDB/microbiomeComputations#81

02/09/24 - all resolved. Data looks good and works!

To Do before asking for review

• Change the hard-coded assay entity ids to a function that just finds the entities with collections.

For testing, please check that there are two collections options in the Correlation (assay x metadata) app.

I've left the Functional Associations correlations app out for now. There are open questions about how to handle that app.

backend work relating to this is now merged

The code changes look good. I'm about to test.

In the mean time, I'll ask: Is there a plan for finding assay entities in a different way? When should we expect the approach in the PR to no longer work?

[dmfalke]

Tested. Looks good!

[asizemore]

Good question. Implementing an isAssay annotation like discussed here is still the plan long term. The approach of finding the entities with collections will work as long as collections live on entities that are all leaves of the same branch of the tree.
