Stop one or more of a campaign's videos from counting toward its results — leaderboard standings, stats and payout eligibility are re-aggregated once for the whole batch before the response returns, so send the entire selection in ONE call rather than one call per video.

Every video id must already belong to this campaign (unknown ids → 404). At least one reasons code is required and a note is mandatory when the reason is other, because the reason reaches the creator. Rejected with 409 when the campaign's results are already final, or when it is a LIVE campaign (scored from live sessions, which can't be excluded individually).

Requires read_write scope and an Idempotency-Key; X-Dry-Run: true echoes the intended change without writing.
