Get Form Field Configurations

GET 
/api/forms/:form_id/field-configurations

Return the filter/sort/group field configurations for a form.

Backs the new Forms ▶ View Submissions tab: the FE filter/group UI asks for this once per form to know which form fields are indexable (filter + sort + group) vs filter-only vs display-only, plus the operator set and any dropdown options to render.

Mirrors the shape of /api/task-fields/configurations but is computed per-form from the form's nodes JSONB array.
