Change status or budget on many LinkedIn campaigns (ad sets)

Applies one status or one daily budget to up to 50 campaigns (ad sets in Campaign Manager) at once, reporting each campaign's result separately. Use when: the user has decided the same thing about several named campaigns — pausing a whole test, or standardising a budget. It is one approval instead of twenty. Do not use it to apply a budget the user has not named per campaign: the same figure across different audiences is rarely right, and "£50 each" across ten campaigns is £500 a day. State the total in the confirmation. Do not use it to pause an entire account — pause the campaign group (the Campaign Manager campaign) instead, which is one reversible change rather than fifty. Do not treat it as atomic. LinkedIn is called once per campaign, so a failure partway leaves earlier campaigns changed; the result lists exactly which succeeded and which did not. Never re-run the whole batch after a partial failure — re-run only the failures. Returns per-campaign success or failure with the reason.
