## Summary

Fixes the filter buttons for the summary badge icons on the traces
document source profile, so that in ES|QL mode, the filters correctly
add the field query without defaulting to casting the field value to a
string.

Closes elastic#226414

## How to test

- Enable the Observability mode on the space you are in, navigate to
Discover and enable the ES|QL mode
- Query for a `traces-*` index, `remote_cluster:traces-*` if using
edge-oblt-ccs.
- On the summary column, click on a badge icon and add a filter to the
query.
- The field value should be in its assumed format and not being casted,
such as a `span.duration.us` should be as a `number`, `service.name` as
a `string`.
