Update MediaListParams test expectations to match generated field order

Fix failing tests by updating expected query parameter ordering to match
the macro-generated trait implementations which follow struct field order.

Changes:
- Move parent_exclude parameter to appear directly after parent parameter
- Update both media.rs and media_endpoint.rs test expectations
- No functional change - only reordering of query string parameters
- All 812 unit tests now pass

The generated macro correctly follows MediaListParams struct field order:
parent → parent_exclude → search_columns → slug → status
