fix(apollo): send sequence add contact_ids/label_names as query params per docs

Apollo documents every field for emailer_campaigns/:id/add_contact_ids as a query parameter with no request body. Append contact_ids[]/label_names[] to the query string instead of the JSON body to match the documented contract.
