Check whether a campaign actually exists and is running

Answers one question with real data: does this campaign exist, is it switched on, and does it have a budget it can spend? Free when Adako has synced history for the account; otherwise it falls back to the platform's own list tool, which is free too, and says which source it used. Use when: a create or a resume has just run and the user wants proof; the user says "nothing is spending"; or you need to confirm state before proposing another change. When not to use: the user wants performance numbers — this is an existence and status check, not a report. Returns exists / status / budget / whether it should be serving, with what to do when it is not. It never changes anything, and never claims a campaign is live without having read it back.
