Update an existing row in a v2 app's collection, replacing its data. Gated by the collection's update role list when it declares one, and by its write list otherwise, so a collection that scopes updates to the row's creator refuses an edit on someone else's row. Pass if_match with the row's current version for an optimistic-locked update; on a version mismatch the relay returns the current row, which is what a retry needs. Returns { row }.
