fix(next): resolve filterOptions by path (#13779)

Follow up to #11375.

When setting `filterOptions` on relationship or upload fields _that are
nested within a named field_, those options won't be applied to the
`Filter` component in the list view.

This is because of how we key the results when resolving `filterOptions`
on the server. Instead of using the field path as expected, we were
using the field name, causing a failed lookup on the front-end. This
also solves an issue where two fields with the same name would override
each other's `filterOptions`, since field names alone are not unique.

Unrelated: this PR also does some general housekeeping to e2e test
helpers.
