local query for history exports

[cat-bro]

Add a local query for history exports. History exports have been recorded in the store_export_association table since they were turned into celery tasks in 2023.

I’d like to add this to the gxadmin code base to make use of built in constructs for filtering options, but for demo purposes I’d like to add this to gxadmin-local.sh.
