Replace campaign-level negative keywords

Replaces the FULL set of campaign-level negative keywords (C.270): the desired list is diffed against what Google already has, and the difference is applied as one `create`/`remove` mutate. Send an empty array to clear every campaign negative. The platform is always discovered from the campaign itself; a non-Google campaign returns 501 rather than 404, whether or not `platform` was sent.

Replace campaign negative lists

Sets the full desired set of shared negative keyword list associations on this campaign. Send listIds=[] to detach all negative keyword lists. Only campaign_shared_set links are changed; the lists and their keywords are preserved. Every list must belong to the campaign customer and have type NEGATIVE_KEYWORDS.
